NOAA-15 - 18, AMSU-A, Lunar Contamination Correction (LCC) and NOAA-18 Antenna Parameter Update, 11 April 2006- Issued: 6 April 2006; time issued 1300 UTC

Topic:
   Updated AMSU-A antenna parameters  for NOAA-18 and information on LCC operations

Date/Time(UTC) Message Issued:
    6 April 2006 1300 UTC

Satellite(s) Involved:
    NOAA-15 - 18

Instrument(s) Involved:
    AMSU-A

Product(s) Involved/Affected:
    All

Date/Time(UTC) of Initial Implementation:
    11 April 2006, TBD  UTC

Details/Specifics of Change:
Beginning with the launch of NOAA-18 we implemented an algorithm to detect and correct Lunar contamination in the AMSU-A instrument data for NOAA-15 through 18. Since the implementation, we have noted that the AMSU lunar correction algorithm and implementation currently do not meet the user expectations, and will require further investigation and fine tuning.  The lunar detection appears to be working fine and flags are set in the level 1b data when the moon is in the AMSU space view.  User software should utilize this  flag in the level 1b data and treat the lunar contaminated data at his/her own discretion.  Meanwhile, ORA scientists will investigate the correction algorithm.  This investigation may take some time before a working algorithm can be developed, given the complexity of the problem.

In an effort to improve the correction ability of the algorithm for NOAA-18's AMSU-A, the instrument scientist has examined the current corrections and is providing a new set of antenna parameters. We plan to implement this change on April 11 along with the normal AVHRR visible calibration update. The actual values to be used are provided below. We are providing test data on the anonymous ftp site (ftp://metroweb.nesdis.noaa.gov/pub/test/). This began with orbit NSS.GHRR.NN.D06095.S1609.E1754.B0451516.GC.

Details/Specifics of Change:

On April 7, 2005 around 1900 UTC, NOAA NESDIS made a change in the Polar
data ingestors to prepare for NOAA-N and to correct some minor problems with
HRPT ingests. The NOAA-N change should be transparent to the user
community. It will enable NOAA NESDIS to ingest the new data on the current
ingestors after the NOAA-N launch. The corrections will also eliminate the
truncation of some of the longer HRPT ingests. This change will increase
the maximum size of an HRPT Level 1B data set by approximately 20 percent.

Details/Specifics of Change:

On April 12, 2005 starting at 1230 UTC, NOAA NESDIS will implement the new
level 1B formats for NOAA-15, 16, and 17. This change will impact all
instruments. Listed below are the last passes that should be processed with
the old format and the first passes to be processed with the new format. We
do not expect an extended delay of data but it is possible that NOAA-16
passes may be held up while we implement the changes. We will resume
processing as soon as possible with the new format.

Last passes with old format (received before 1230 UTC):
NSS.HRPT.NK.D05102.S1143.E1158.B3594040.WI

* Due to scheduling, this pass will not be received until after the switch
to the new format. However, in order to be consistent with the rest of the
data recorded from that orbit, it will be processed in the old format.

First passes with new format (received after 1230 UTC):

Satellite(s) Involved:
NOAA-16

Instrument(s) Involved:
AVHRR...

Product(s) Involved/Affected:
NONE

Date/Time(UTC) of Initial Implementation:
N/A

Details/Specifics of Change:
Due to system problems in generating the coefficient updates for NOAA-16
AVHRR instrument there will be no updatefor the month of April 2004. The
coefficients were provided late and therefore will not be implemented.
However the generated coefficients for April 2004 were not much different
than what is currently being used, hence there would have been very little
change. We will resume implementation of the updated coefficients for
NOAA-16 AVHRR instrument in May 2004 (next month) on the same schedule as
have been done in the past.

Back

NOAA-16 Along Track Error

After observing AVHRR images from NOAA-16 since we turned on corrections
based on a pitch attitude error, we are convinced that the along track error
is not due to a pitch error. The error appears as a clock error.

On Tuesday, April 17, we will switch the level 1B process to correct the
along track error using a +1 second in addition to the normal clock error.
This will improve the earth location data out along the limbs. The
improvement will be most significant in the higher latitudes. The user
will see changes in the earth location data that will improve the quality
with the clock correction offset reflecting a different range from current.
Also, the attitude correction information will become zero with the constant
attitude correction flag set to zero in the header record.

Normally, changes such as this (turning clock corrections on/off; turning
attitude corrections on/off) would be done immediately with short notice to
the user community. These are considered no impact changes to maintain or
improve the quality of the data or to correct problems that are making the
data unusable.

Please notify us, if you need test data. If this will create a problem for
you, please contact either myself or Vincent Tabor (Vincent.Tabor@noaa.gov
or phone 301-457-5247). Cecil Paris is on detail to another office for at
least 60 days and will not be available to address your inquiries.

Thank you.

Development of a Generic Notification Policy

The Information Processing Division has a notification policy in place
that covers current user problems related to calibration, navigation,
and level 1B data. Currently, we notify the user community, data
archive centers, instrument scientist, etc. when problems occur. They
are provided with information related to the specific nature of the
problem, when the problem appeared, when the problem was resolved,
specifics on the resolution of the problem, or status on events related
to the problem. There are occasions when IPD is informed by a data user
of a problem before it is detected internally. Appropriate action is
taken to verify the problem, to proceed with resolution and user
notification. Any information is posted on the Pre-Product Processing
web site and is sent out to direct readout users by Wayne Winston.

In response to user requests, Tom Renkevens and Emily Harrod are working
together to formulate a generic notification policy. This policy will
not only cover notices related to problems but also include notices of
plans and operational updates or changes. A first draft of the proposed
policy is attached (in WordPerfect, MS Word, and DOS text format).
All OSDPD Product Oversight Panels (POP) have been asked to review the
attached draft. If you have been contacted by your respective POP,
please ignore this message and reply to their inquiry. There are
several individuals/organizations that are not represented by a POP who
depend on level 1B data and other NOAA data that will be impacted by
this new policy. Please review the policy and forward your comments
back to me (Emily.Harrod@noaa.gov). Unfortunately, we have a short turn
around time and need your input no later than April 18. We appreciate
your taking the time to give us your input and will be sure to include
it in our decisions to update the proposed policy. Thank you for your
support.
Emily

---------------------------------------------------------------------
Date April 4, 2002

POP Co-chairs:

Per a long standing Action (see below) from the Satellite Products and
Services Review Board
(SBSRB), this memo is to establish more formal procedures on the
notification procedures from
Product Oversight Panels (POPs) for product changes, outages (GOES or POES),
or
instrument problem alerts to users. Valuable information was received from
a number of POPs
outlining any existing procedures used by the POPs for notifying customers
as to these product
changes, outages (GOES or POES), or instrument problem alerts. A common
thread among the
responses was 'email notification' with also some internet based postings.

One of the problems that some users had was that messages were received in
varying formats
which can be confusing to the users. The goal of this action is to
establish a common format that
can be used by the POPs in the email dissemination to each POP's unique
customer email list.
By keeping the existing POP's unique customer email list(s), this will
prevent the over saturation
of information to users who are not interested in certain product areas.

However, it is proposed that all email messages will be posted to a common
web site so all users
can view email message from all POPs. This web page will be hosted by the
Satellite Services
Division, with links from the SPSRB web site. SSD is currently undergoing a
migration to new
web servers. Once this transition is complete, the POP members responsible
for disseminating
information will only need to add one email address to their email lists
(email address will be
forthcoming in the future). An example of a similar web site can be seen at
the SSD Bulletins
Page: http://www.ssd.noaa.gov/PS/SATS/bulletins.html

Attached is a format for message dissemination. In addition to a common
format used by the
POPs, a common time line for the dissemination of information shall be
established, based on the
degree of action needed by the user of the data. The more user
modifications that are required,
the longer the lead time for notification.

Please review the proposed format and survey your user community. After all
POP and user
comments are received, appropriate actions will be taken, an implementation
date will be set, and
a notice issued. The final format will be added to the website. Please
return your comments no
later than April 18, 2002 to Thomas.Renkevens@noaa.gov. If you have
questions please
contact Thomas.Renkevens@noaa.gov (Phone 301-763-8081 ext 109) or
Emily.Harrod@noaa.gov (Phone 301-457-5247). Thank you for taking the time
from your busy
schedule to assist us in completing this task.

Action: The Level1b Update Notification Policy Team will develop draft
procedures and
formats for notification of users when changes occur. This procedure and
form may be used as a
prototype for all POPs when notifying users of changes, in order to apply
some consistency to the
notification process. They will coordinate with SSD on this issue (T.
Renkevens/E. Harrod).

Minimum Notification Time Table if no procedures are currently in place

Use current POP procedures tailored to current customers base should those
customers request
additional notification with greater frequency.

Major Change (those that require user modification)
at least 2 months, offering of sample dataset if applicable
Reminder in 1 month, 1 week, and within 1-2 days
Summary of results within 1-2 days after change occurred
Indicate Parallel testing where applicable
Minor Change (product upgrade, no user modification needed):
2 weeks
Reminder within 1-2 days
Summary of results within 1-2 days after change occurred
Short Notice Change (example: Rapid Scan Operation - a temporary change
to current
operations)
Immediately before implementation
Emergency Change, Outage, or Instrument Problems
Immediately after implementation
Updates with any new information

Common Format for Message Dissemination

NOAA-15, AMSU-A, Channel-11 Problems

At 19:32z , JD 100, 10 April 2002, the AMSU-A channel 11 detector output
changed rendering the data unusable. All readings of Space, Warm Target
and Earth counts are approximately 7195 counts. No other parameters
seem to be affected at this time. SOCC and instrument scientists have
been notified of our observations. We will continue to monitor and
investigate the problem. The user community will be notified of any
changes. Attached is a WordPerfect file produced by Robert Levin that
highlights the problem showing plots of data starting just before the
problem occurred.

NOAA-16 Along Track Error Corrections

After observing AVHRR images from NOAA-16 since we turned on corrections
based on a pitch attitude error, we are convinced that the along track error
is not due to a pitch error. The error appears as a clock error.

On Tuesday, April 17, we will switch the level 1B process to correct the
along track error using a +1 second in addition to the normal clock error.
This will improve the earth location data out along the limbs. The
improvement will be most significant in the higher latitudes. The user
will see changes in the earth location data that will improve the quality
with the clock correction offset reflecting a different range from current.
Also, the attitude correction information will become zero with the constant
attitude correction flag set to zero in the header record.

Normally, changes such as this (turning clock corrections on/off; turning
attitude corrections on/off) would be done immediately with short notice to
the user community. These are considered no impact changes to maintain or
improve the quality of the data or to correct problems that are making the
data unusable.

Please notify us, if you need test data. If this will create a problem for
you, please contact either myself or Vincent Tabor (Vincent.Tabor@noaa.gov
or phone 301-457-5247). Cecil Paris is on detail to another office for at
least 60 days and will not be available to address your inquiries.

Thank you.

NOAA-15 AMSU-A Channel-11 Problem Update

Update from the SOCC SATOPS Morning Report April 12, 2002:
"On Wednesday, April 10 at ~19:30z, the NOAA-15 AMSU-A1 channel 11 signal
dropped dramatically. In the hours preceding the anomaly, channel 11 behaved
normally, its value varying periodically with orbital position between
~18600 and 18000 counts. At ~17:50z the pattern changed and by 18:45z it
began to drop steadily. Finally at ~19:30z channel 11 dropped instantly from
16500 to 7195 counts. Since then it has been steady between 7196 and 7194
counts. So far the engineering investigation has not revealed any other
abnormalities in AMSU data or spacecraft data that coincide with this
anomaly, but they are continuing to look into the matter."

Date/Time(UTC) of Initial Implementation:
18 April 2005, 1537 UTC

Details/Specifics of Change:

SOCC has announced that on April 18 at 1537 UTC they plan to switch
NOAA-16's TIP from side 1 (id = 3) to side 2 (id = 4). This is likely to
result in a 5 to 10 minute loss of data on rev 23566. Details follow.

"The ana log TIP telemetry on NOAA-16 is drifting upwards at a rate of one
count approximately every 150 days. This is the same phenomenon that was
seen and rectified on NOAA-15. The drift is generating yellow limit
violations and closing in on some red limits. To rectify this situation,
the TIP is to be switched from side 1 to side 2. ....
Therefore, on April 18, 2005 we are planning to switch NOAA-16's TIP from
side 1 to side 2. We have scheduled a pass with no playbacks of recorded
data so that we have time available to ensure that the switch will occur
nominally. However, since the TIP switch will affect all telemetry and
data, we will lose instrument recordings for part of that contact. Most
likely on the order of 5-10 minutes of data lost. some of this data not
recorded on the DTRs will be captured from HRPT. the pass is scheduled for
April 18th at 15:37z, or 11:37 pm EDT. The contact is rev 23566 at
Fairbanks CDA."

Please hold up on changes to your system to the new format. We are
investigating a concern that may result in the delay of the update. We will
get back to you as soon as possible (within 15 to 20 minutes) on whether or
not a delay will occur. Thank you for your patience.

*********** Original Message follows *************
On April 12, 2005 starting at 1230 UTC, NOAA NESDIS will implement the new
level 1B formats for NOAA-15, 16, and 17. This change will impact all
instruments. Listed below are the last passes that should be processed with
the old format and the first passes to be processed with the new format. We
do not expect an extended delay of data but it is possible that NOAA-16
passes may be held up while we implement the changes. We will resume
processing as soon as possible with the new format.

Last passes with old format (received before 1230 UTC):
NSS.HRPT.NK.D05102.S1143.E1158.B3594040.WI

* Due to scheduling, this pass will not be received until after the switch
to the new format. However, in order to be consistent with the rest of the
data recorded from that orbit, it will be processed in the old format.

First passes with new format (received after 1230 UTC):

memo issued by SOCC that addresses the procedure to be followed, identifies
the orbits and times for testing over the 4 day period, and identifies the
impact to user community. Below is a general description of what will
occur.

"During the week of April 19th, NOAA-15 is being used to test reduced gyro
software that is installed on all NOAA-KLM spacecraft. The test exercises 5
modes of operation, testing each type of control mode. We are performing
the test in case the gyros on this series of spacecraft degrade to such a
point where one axis of control must be estimated. This will happen if we
lose another gyro on NOAA-15 for instance. ...
... we are testing the attitude software, so there may be pointing errors
during the test."

Product(s) Involved/Affected:
No immediate impact/possible HIRS

Date/Time(UTC) of Initial Implementation:
14 April 2004, Time 1515 UTC

Details/Specifics of Change:
On April 14 (day 105) on orbit 18343 around 1410 UTC, the Satellite
Operations Control Center (SOCC) disabled TCE24 (AVHRR Heater/Louver).
This was done as one step toward efforts to improve the AVHRR data.
Disabling the TCE24 will cause the AVHRR to heat up. This could result in
AVHRR scan motor improvement and better imagery. It is possible that the
HIRS will heat up resulting in an increase in channel noise. The data will
be closely monitored.

From: "Charlie Vance"
Organization: NOAA

At 16:00 Z SOCC turned off the Aydin Frame Synchronizers and put the GDP
Space Systems' Frame Synchronizers in their place. The GDP Frame Synchs
were turned on at 16:35Z and the first data received:

from Wallops CDA was a delayed STIP:
| 1547 | N-11 STIP 3B 64769 W |
NSS.TIPS.NH.D01106.S0809.E1200.B6476567.WI |

NOAA-16 Level 1B Update - Implementation Time

On April 17, 2001, the following update will go into operation for
NOAA-16 Level-1B:

We will switch the level 1B process to correct the along track error
using a +1 second in addition to the normal clock error. The user will
see changes in the earth location data that will improve the quality
with the clock correction offset reflecting a different range from
current. Also, the attitude correction information will become zero
with the constant attitude correction flag set to zero in the header
record.

The change will be made between the hours of 11:00am and 12:30 pm
local. The last passes processed before the change will be:
NSS.LHRR.NL.D01107.S0919.E0926.B0293333.GC
NSS.HRPT.NL.D01107.S1447.E1502.B0293636.GC
NSS.GHRR.NL.D01107.S1300.E1447.B0293536.GC
All data with time periods after the above passes will be processed
using
the changes.
Please contact us if you have any questions or concerns.
Thank you.

Details/Specifics of Change:
On April 14, SOCC issued the following bulletin announcing the NOAA-15 TIP
side 1 to side 2 swap on April 24 during the 1743UTC pass.
"The analog telemetry on NOAA-15 is drifting upwards at a rate of one count
approximately every 150 days. The current value is beginning to generate
yellow limit violations and close in on the red limits. To rectify this
situation, the TIP is to be switched from side 1 to side 2. .... On April
24, 2003, we are planning to switch NOAA-15's TIP from side 1 to side 2. We
have scheduled a pass with no playbacks of recorded data so that we have
time available to ensure that the switch occurred nominally. However, since
the TIP switch will affect all telemetry and data, we will lose instrument
recordings for part of the contact. Most likely on the order of 5 - 10
minutes of data lost. The pass is scheduled for April 24th at 1743Z ...
Currently only one DTR (degital tape recorder) will be in active during that
contact. The data lost will be on GAC 2B. Additionally, the scheduled
playback of DTR 1A during rev. 25708 is postponed until rev. 25709. Thus,
the data from 1A will be delayed approximately 100 minutes."

Official notification from SOCC reports: "At approximately 13:00Z on Sunday, 17 Apr, the N15 HIRS filter motor current soared to red high limits of 320+ mAmps. This surge was accompanied by greatly increased temperatures as well as very erratic period monitor values and intermittent loss of filter wheel synch. At 14:52Z, ..., EMOSS engineers turned on the HIRS filter motor heater. Shortly thereafter, the filter motor current surged again to its highest levels ever (408 mAmps) with accompanying high temperatures and a steady loss of filter wheel synch. Plans are to turn the heater back off on Monday, 14:20Z to determine if this will improve the HIRS situation. If it does not, a downgrade in status to RED is under consideration. Additional information will be provided as it is obtained. It is assumed that all HIRS products are degraded at this time..."

Follow-up report: "Imagery was OK at the start of the major surge (17 Apr 13:00Z), and completely corrupted on all channels on the next pass at 14:40Z (the same pass heater turnon occurred) and remained corrupted through the most recent pass today at 14:20Z after heater was turned back off."

SOCC engineers continue to monitor and investigate the anomaly.

Details/Specifics of Change:

SOCC is reporting the following:
N15 HIRS filter wheel motor current, jumped suddenly by 20 mA at 01:35 UTC
today (day 110). Over the next several hours the current rose more
gradually to as high as 302 mA. At 02:05 UTC the period monitor began to
show excursions beyond its nominal range and at 03:13 UTC the filter wheel
began to lose sync intermittently. During later passes the motor current
and temperature, as well as the housing temperature began to flag. To begin
the correction process, the filter heater was turned on during the 12:50 UTC
pass. It is planned to leave it on until the motor current comes down and
the synch word and period monitor become more stable. This usually takes a
few days. Users will see increased noise in the data. SOCC and IPD will
continue monitoring.

To minimize the impact on the level 1B data, normal updates of the 24 hour
calibration file have been suspended to prevent contamination. Also, lunar
intrusion detection will be turned off to prevent incorrect flagging of the
data.

Details/Specifics of Change:

SOCC reports the following:
"AT approx 05:30Z today (Tuesday 20 Apr 04) after MIRP rephase, the AVHRR
scan motor current surged very briefly to pegged (305 mAMps) and synch delta
pegged out (where it remains). It quickly came back to about 275, below
where bar codes are usually seen. However, since that surge, all images are
fully bar coded, even though the scan motor current has settled down again.
In the hope of getting images back to nominal SOCC will be manually
rephasing the MIRP for approx 10 seconds at 14:30Z (10:30 local) today."

Users will see scan line drop outs when the rephase occurs. Checking "bit
1: resync occurred on this frame" in the data record quality indicators will
tell you when the rephase occurs.
"bit 29: data gap precedes this scan" indicates the gap created by the
rephase in the scanline after it occurs.

Satellite(s) Involved:
NOAA-15, 16, 17

Instrument(s) Involved:
All instruments

Product(s) Involved/Affected:

Date/Time(UTC) of Initial Implementation:
27 April 2005, TBD UTC

Details/Specifics of Change:

The implementation of the new level 1B format has been rescheduled for
Wednesday, April 27th. In working with the HIRS instrument scientist and
the National Weather Service, we have accounted for additional anomalies
seen in the NOAA-15 HIRS data. We have updated the user format
documentation to help you better understand and apply the calibration
anomaly flags. The new/updated flags should have no impact on users
even if you are using the old software, unless you are always checking
the channel flags regardless of what the scanline flag, bit 6,
indicates.

Updated format documentation is found on our anonymous ftp site:
ftp://metroweb.nesdis.noaa.gov/pub/noaa-n/HIRS
in the file named HIRS1bFormat.doc.

A separate email will be sent when the test data is available.

The new HIRS 4.0 algorithm improves the calibration accuracy when the
instrument filter temperature is changing rapidly, as is often the case
for NOAA-15 and occasionally for NOAA-16 and 17. During normal
operations, the difference in the radiances produced by the two
algorithms is very small (within noise spec.).

Below is information to help you in determining if a change is needed in
your HIRS software.

1. Calibration Quality Flags (channel flags in bytes 37 through 76)- The
order of the flags between the operational version and the new
version are different (they are set based on the same specification).
The operational version has them stored in the wrong order. It has the
flags stored in channel sequential order. The KLM documentation states
that these flags are stored in the same order as the telemetry (Channels
1, 17, 2, 3, 13, 4, 18, 11, 19, 7, 8, 20, 10, 14, 6, 5, 15, 12, 16, 9 ).
On March 11, 2005, the parallel test data were modified to report the
flags in telemetry order in the level 1B.

2. Quality Indicator Bit Field - "Bit 28: insufficient data for
calibration (see below)" - is not changed, but corrected to match the
description. Users should follow the direction to check the additional
flags indicated in the document.

3. Scan Line Quality Flags [Calibration Problem Code] - "bit 6:
anomalous space or BB view data, calibration slope value came from the
HCF, or some QC tests could not be applied in some of the IR channels" -
The definition is changed but the function is the same as that of the
previous version.

4. Calibration Quality Flags -
bit 5: calibration failed
bit 4: anomalous space or BB view data
bit 3: calibration slope value came from the HCF
bit 2: BB views failed NEDC test
bit 1: space views failed NEDC test
bit 0: some QC tests could not be applied
These channel flag definitions were made practical and have no major
impact on users unless they are checked regardless of bit 6 value above.
"bit 4: anomalous space or BB view data" is a summary of bits 0 and 3.
We have found that bits 1 and 2 reflect when data exceeds instrument
specification, however, most of time the data is still useful and causes
the user to throw away good data. We are suggesting that you follow this
sequence when checking the channel bits:

If "bit 6" = 0 then continue processing
If "bit 6" not = 0 then check the channel flags (ch_flag)
If "ch_flag" = 0 then continue processing
If "ch_flag" > 6 then follow your normal problem path (checks bits 3 - 5)

Please contact us if you have questions or concerns.

You must forgive the redunancy of this message, in a rush to give ample
notice mistakes are made easily...the satellite involved is "NOAA-16".

The previous email did not mention that the MIRP rephase would affect all
instruments. Users should see scan line drop outs when the rephase occurs.
Any user feedback on the improvement (or lack of) in AVHRR imagery following
the rephase would be greatly appreciated.
Thank you for your support.

LHRR.NM.D05112.S1212.E1224.B1469292.WI

Due to the recent problems with the NOAA-15 HIRS instrument filter wheel motor, IPD and ORA agreed that NOAA-15 HIRS instrument calibration would be turned off in the new system to ensure that all data are flagged properly and to prevent further calibration contamination. Calibration will resume when the NOAA-15 HIRS improves.

Details/Specifics of Change:
Test data with the final changes went into the parallel test system on Friday, April 22. The changes were all related to improving our method of setting flags in the HIRS data. However, we turned off calibration of the NOAA-15 HIRS to eliminate calibration problem due to the current status of the instrument. Please revisit your systems and verify that they are functioning properly. We have one report of a problem which we are working with the user to resolve. We are working toward implementing the changes on Wednesday, April 27th between 1300 and 1400 UTC. But, please watch your email for possible slip and a notice with more details on the initial passes affected by the change.

Please contact us if you have questions or concerns.

Details/Specifics of Change:

SOCC has reported re-occurance of the barcode pattern in the AVHRR imagery
for NOAA-16. Once again a MIRP rephase will be required.. the rephase will
occur at the implementation time indicated above in this message..

Users will see scan line drop outs when the rephase occurs. Checking "bit
1: resync occurred on this frame" in the data record quality indicators will
tell you when the rephase occurs. "bit 29: data gap precedes this scan"
indicates the gap created by the rephase in the scanline after it occurs.

The MIRP rephase will affect all instruments. Users should see scan line
drop outs when the rephase occurs. Any user feedback on the improvement (or
lack of) in AVHRR imagery following the rephase would be greatly
appreciated.

Thank you for your support.

    All Products

Date/Time(UTC) of Initial Implementation:
    25 January 2006, Time 1930 UTC

Details/Specifics of Change:
On January 25, the level 1b processing was updated to include cloud mask information.  At that time the header record was updated to use a spare byte as a flag to indicate when CLAVRx processing was turned on.  The original message that follows, did not include the fact that this was considered a level 1b version change.  The version number contained in the header was updated from 3 to 4.  All level 1b documentation should reflect that as of January 25 the version number will read, version 4, until another change is made.  Several users have expressed concern that the change was unexpected and caused them processing problem.  We regret any problems that you may have experienced and will endeavor to be more detailed in future notices. 


****Original Message from January 25, 2006****
On January 25, NOAA updated AVHRR level 1b processing so that the reserved CLAVR-x  (Clouds from AVHRR Extended cloud mask) bytes are utilized and the announced 1B converter changes are in operation.

****** Information from previous announcement ******

A new flag was added to  the header record (utilizing spares) that indicates when the CLAVR-x processing is actually turned on or off. A brief explanation of the CLAVR-x is provided below along with a list of the affected level 1b bytes. Also, you will find a brief explanation of the 1B converter change.  Though we believe this to be a no impact change, we are asking that you please monitor your systems carefully over the next few days. d89nav


The CLAVR-x provides the cloud mask present in the AVHRR level 1b datasets. It was designed to operate under all conditions including all orbital configurations. The goal of  the CLAVR-x cloud mask is to provide a useful first guess cloud mask for all AVHRR applications that require it. It is constrained to perform this task in a timely manner to avoid delays in subsequent AVHRR  applications. The CLAVR-x cloud mask in level 1b data is stored as a 2-bit value for each pixel . The values of the cloud mask are 0= clear,1 =probably clear, 2= probably cloudy and 3 = cloudy. The cloud mask is a series of spectral and spatial tests based on a long heritage of AVHRR cloud detection within NESDIS. In addition to providing the 2-bit cloud mask in the level 1b data, the results of each CLAVR-x test are also available in HDF files to allow for application specific optimization of  the cloud mask.  A draft of the CLAVR-x cloud mask theoretical basis document can be found at http://cimss.ssec.wisc.edu/clavr/clavrx_docs/clavrx_mask_atbd.pdf .

The CLAVR specific bytes in the level 1B file are outlined below. This information can be found in the NOAA-KLM Users' Guide (http://www2.ncdc.noaa.gov/docs/klm/html/c8/s83-1.htm) under the NOAA-N  format information.

The following gives a description of the changes to the converter:
A problem with certain data values in 1b data sets has been reported by users. This problem involves 1-, 2-byte or 4-byte data fields where a valid data value has the most significant bit set, with all other bits 0. Therefore, values affected are 1-byte fields with a valid signed integer value of –128, 2-byte fields with a valid signed integer value of –32768, or 4-byte fields with a valid signed integer value of  –2147483648. These values may be erroneously stored as 0 in the 1b. The 1b fields which have been reported as occasionally erroneous are AMSU-B and MHS radiometry values and HIRS minor frame bit flags and minor frame header elements. See December 13 notice for more details.

NOAA-16 and 15 Level 1B

Users reported problems processing the NOAA-15 and 16 HRPT and LAC
data. The problem was traced to fill data that was not zero filled.
Sensor data word 3414 and spare word 3415 (bytes 14919 - 14924) contain
spare bits that are not zero filled as specified in the level 1B
format. The problem was corrected in the preprocessor software. No
other level 1B data is affected by the change. This is considered a no
impact change and we plan to put the change into operations on tomorrow,
May 1, 2001 between the hours of 10am and 11:45am local time.

The first orbits to be processed after the change are:

On April 29, SOCC issued the following notice.
"NOAA-14 hardware autonomously switched the power supply electronics to
backup. At 0512z on DOY 119, April 29, 2003, NOAA-14 experienced a
momentary 28v bus voltage in excess of 29 volts. This triggered an
autonomous switch of both the PSE mode controller and boost regulator from
primary to backup. Engineering analysis indicates this was most likely due
to degraded shunt performance. On orbit 42939, the Solar Array offset value
was commanded to –55 degrees to reduce the power. At a later date, when
shunt performance has stabilized, the mode controller and boost regulator
will be commanded back to primary." Users may notice data changes as
instrument temperature may go up or down due to the solar array shadow
moving.

Removal of HIRS from ATOVS Processing

I am sending this message for information purposes only.....

At 19:46 UTC June 8,2000 we modified the ATOVS system to not use the HIRS
data in
processing. This was done by modifying cloud detection thresholds to flag
all retrievals as cloudy and by removing the HIRS channel 2 from the
retrieval generation step. We continue to use the HIRS to co-locate the
AMSU-A to the HIRS footprint, but we do not use the channel data in our
processing. Again, the high quality of the cloudy AMSU-A only soundings
continues and I encourage your continued use of these products.

The HIRS instrument has not improved it's status after the filter wheel was
put in high power mode. The filter wheel continues to slip which causes a
shift in the brightness temperatures. The instrument scientists continue
to troubleshoot the problem. While we are hopeful the instrument will
return to a useable state, we are taking precautions in case it does not.

I will keep you advised of changes as I learn of them.

Sincerely,
Ellen Brown
Product Area Leader for Soundings

KLM/ATN Timing Discrepancy - Along Track Anomaly

The Satellite Operations Control Center discovered a problem that
apparently resulted in the introduction of a 900 millisecond timing
error for both NOAA-15 and 16. This will account for the constant along
track error that is currently corrected at the user level. Exerts from
Peter Phillips message are provided below to fill you in on some of the
details. On August 7, SOCC plans to correct the error and perform a
clock update to remove the 900 milliseconds. At that time we will
update our clock drift file to remove the 1 second corrections that we
have been applying to the NOAA-15 and 16 data. Direct readout users
that are correcting their data should do the same. As soon as the
expected error parameters are received from SOCC, a new clock drift file
will be placed on our web site to reflect the change.

Message dated July 26, 2001 from Peter Phillips:
"In preparation for ordering new frame synchs for the CDAs, yesterday we
started reviewing the present frame synch settings for all data types.
We came across a very interesting discrepancy when we compared the
blocking factor settings for real-time TIP data. For ATN satellites,
PACS sets up the frame synch to collect 5 frames of data before passing
the data over the HDLC interface to the Comm Controller. For KLM
satellites, PACS sets up the frame synch to collect 11 frames.

This difference in these settings is significant because Ground Receive
Time (GRT) is not stamped on the TIP frames until they arrive at the CDA
Comm Controller. GRT is used in the calculation of the spacecraft clock
error, which is the difference between TIP Time and GRT. ...
When calculating the clock error, PACS adds a correction factor to the
TIP Time (same as subtracting from GRT) to account for the delay. This
correction factor is a constant value of 400 milliseconds that does not
vary whether the data is KLM or ATN.

Based on the relatively good correlation between SOCC and CEMSCS
estimates of the spacecraft clock error for ATN satellites, this
correction factor appears reasonable for the ATN blocking factor setting
of 5 frames. However, this correction factor is not adequate for the
KLM setting of 11 frames. Based on frame synch tests performed at SOCC
in 1999, a delay of 150 milliseconds is introduced for every additional
frame of data that is collected in the frame synch. Therefore,
collecting an additional 6 frames will lead to an additional delay in
stamping GRT of approximately 900 milliseconds. This will cause the
SOCC reported spacecraft clock error to be 900 milliseconds less than
the true value for KLM spacecraft.
Because the spacecraft clock error is used as the basis for setting the
spacecraft clock, the net effect of this discrepancy will be that the
spacecraft
clock will be set 900 milliseconds AHEAD of the true value....
This, in turn, would cause the AVHRR imagery to appear to be lagging the
calculated spacecraft position by nearly 1 second, which is the problem
users have seen on KLM spacecraft.

SOCC engineers and operators confirmed this phenomenon today on a
NOAA-15 pass at Fairbanks. As expected, PACS set up the frame synch to
buffer 11 frames of data. The reported TIP clock error was -200
milliseconds. Midway through the pass, the operators changed the buffer
setting to 5. The reported TIP clock error changed to +700
milliseconds. The operators then returned the buffer setting to 11, and
the reported TIP clock error returned to -200 milliseconds. These
results indicate that the "true"
clock error on NOAA-15 is approximately +700 milliseconds, not -200
milliseconds as we have been reporting up to this point.

SOCC engineers will perform a similar test on NOAA-16 Friday morning to
ensure the results are consistent for all operational KLM spacecraft.
If they are consistent, PACS software can be corrected through a PIR to
change the frame synch blocking factor setting to 5 frames for KLM TIP
data, and the spacecraft clocks can be corrected by -900
milliseconds--or whatever amount is necessary to bring the "true" error
to zero--in a coordinated manner between the SOCC engineers and user

NOAA-15 and 16 Elapsed Time Clock Up

Following is the bulletin issued by SOCC announcing their intentions to
correct the NOAA-15 and 16 elapsed time clocks. The Information
Processing Division will update the level 1B preprocessor replacing our
current adjustments at the same time. The level 1B user should not be
impacted by the update. Direct readout data users should update their
systems accordingly.
Thanks
Emily

"Due to a configuration error in ground equipment, the TIP clock errors
that are being reported for NOAA-15 and NOAA-16 have been determined to
be inaccurate by –900 milliseconds, i.e. actual clock errors are 900
milliseconds greater than the values being reported. The NOAA-15 TIP
clock is now reading –100 milliseconds and the NOAA-16 TIP clock is
reading +100 milliseconds. The actual errors are: NOAA-15 = +800
milliseconds, NOAA-16 = +1000 milliseconds. It is necessary to subtract
1.0 second from both spacecraft clocks to correct this error. These
corrections will take place on August 7th, 2001 via SCT at 23:59:00Z for
the control OBPs. The standby OBPs will be updated via real time
command (in the schedules)."

Details/Specifics of Change:
On August 21, SOCC is planning to change the solar array offset from
-45 to -55 degrees. NOAA-14 has recently entered full sun. Because the
battery charges are no longer drawing significant current, excess power
is being generated by the solar array. This array movement is to reduce
the excess power generation, so as to reduce operational stress on the
power dissipation shunts. NOAA-14 will remain in full sun until April
of 2004.

MEMORANDUM FOR: All NOAA-17 Level 1B Data Users

FROM: Barbara A. Banks
Chief, Information Processing Division

SUBJECT: Operational Status of NOAA-17 Level 1B Data

On August 24, the Information Processing Division (IPD) will declare all the
National Oceanic and Atmospheric Administration (NOAA)-17 level 1B data
operational. These data are available to the user community:

AVHRR Advanced Very High Resolution Radiometer
HRPT - High Resolution Picture Transmission
LAC - Local Area Coverage
GAC - Global Area Coverage
AMSU-A Advanced Microwave Sounding Unit-A
AMSU-B Advanced Microwave Sounding Unit-B
HIRS High Resolution Infrared Radiometer
SEM Space Environment Monitor
DCS Data Collection System
SAR Search and Rescue
SBUV Solar Backscatter Ultraviolet Spectrometer

The following anomalies in NOAA-17 data have been identified and corrected
or will be corrected in an operational mode.

HIRS - On July 11, as of orbit B0023637, the scan mirror temperature sensor
failed completely. Prior to this, it was intermittent. This should have no
impact on level 1B and product processing. Michael Chalfant, Office of
Research and Applications (ORA), examined imagery produced from NOAA-17 HIRS
data and made recommendations for updates to the level 1B processing.

On the afternoon of July 11, the following changes were introduced into
operations.
1. Due to possible contamination in the space view samples, the number of
space view samples used in processing has been reduced from 45 to 40 making
it compatible with NOAA-16.
2. A constant roll type attitude correction of 1.8 degrees was introduced
to correct an apparent across track error that appears to be the same as in
NOAA-16.

AMSU-A - Channel 3 is demonstrating intermittent 30 count drops in the space
and warm target values during the descending portion of some orbits.
Internal data users indicate that this does not create a problem for their
product processing. The National Environmental Satellite, Data, and
Information Service (Satellite Operations Control Center - SOCC, ORA, and
IPD), and the National Aeronautics and Space Administration are working
together to determine the source of this anomaly. Dr. Tsan Mo, ORA
instrument scientist, has recommended a software fix for the level 1B
processor calibration coefficient computation. IPD will integrate, test,
and implement this change as a normal operational update. Users will be
notified when test data is available.

One final item of note for the level 1B and direct readout data users.
Clock error adjustments for NOAA-17 are being handled in a different manner
than for the other NOAA polar satellites. On July 30, SOCC began making
daily updates to the spacecraft clock to account for the drift error (daily
corrections of 0.6 msec). The current drift rate is about -0.7 msec/day.
SOCC will continue to monitor the clock error closely. Users will be
notified of any changes.

NOAA-17 beacon TIP switching to investigate AMSU-A1 channel-7 noise
spikes

Date/Time(UTC) Message Issued:
26 August 2003/ 1220 UTC

Satellite(s) Involved:
NOAA-17

Instrument(s) Involved:
AMSU-A1 (could affect others)

Product(s) Involved/Affected:
Soundings, Level 1B, channel-7 data

Date/Time(UTC) of Initial Implementation:
28 August 2003, 1920 - 1935 UTC

Details/Specifics of Change:
NASA/GSFC has requested a special test as part of the investigation into the
NOAA-17 AMSU-A1 noise spikes on channel-7. They have requested that IPD
specifically observe the AMSU data (the Space View and Internal Warm Target
counts) during the test period to identify any coincident changes or science
data contamination on channel 7. Their request indicates the following:
"The instrument vendor performed a Root Cause Analysis which concluded that
radio frequency (RF) interference in the frequency range of 10 - 200 MHz
could be a possible cause of a problem. A joint connecting the channel 7
mixer to its intermediate frequency (IF) amplifier is known to have low
margin for rejection of this signal. ... the on-orbit interference could be
due to the proximity of NOAA-17 to other satellites broadcasting at a
frequency around 137.5 MHz."

NOAAs SOCC reports that the requested test will be performed on August 28.
During the time period from 1920 UTC to 1935 UTC, the following procedure
will be performed:
"Turn off the N17 beacon transmitter 2 for 5 minutes. Then, turn on beacon
transmitter #1 for 5 minutes, turn it off for 5 minutes, and finally turn
beacon transmitter 2 back on (it is the normal operations beacon
transmitter)."

Users are asked observe their data carefully during this time period and
please contact us with problems or concerns. Thank you for your patience
and support.

Details/Specifics of Change:
Previous messages gone out concerning the changes to the 1B format have
mostly referenced changes to be made to NOAA-N. This is a reminder that
changes will affect the NOAA-KLM satellites 1B formats as well. Plans are to
implement new operational algorithms i.e lunar correction, and calibration
that will affect the KLM series as well as NOAA-N. These changes are
expected to be ready for implementation prior to the NOAA-N launch.
Therefore, it is important to review the formats listed on this
website:ftp://metroweb.nesdis.noaa.gov/pub/noaa-n in order to review the
"1B Diff" file. This is a reminder that users should also begin addressing
1B format changes as they affect the KLM series as well. The website
provides the changes to be incorporated in the KLM series as well.

The new calibration coefficients for NOAA-16 AVHRR Channel 1 & 2 for
September 2003 are:

Ch_1_lo = .05309*count - 2.047, count<498.96
Ch_1_hi = 0.1550*count - 52.67, count>498.96

Ch_2_lo = .05750*count - 2.172, count<500.16
Ch_2_hi = 0.1694*count - 58.15, count>500.16

where COUNT is raw 10-bit count. These coefficients are expected to be
optimal on September 27, the middle point between the scheduled updates on
September 9 and October 14.

NOAA-15 and 16, HIRS Visible Calibration Update - Rescheduled.

Date/Time(UTC) Message Issued:
29 August 2002 2030 UTC

Satellite(s) Involved:
NOAA-15 and 16

Instrument(s) Involved:
HIRS

Product(s) Involved/Affected:
Level 1B and 1B*

Date/Time(UTC) of Initial Implementation:
5 September 2002

Details/Specifics of Change:
The HIRS visible calibration update scheduled for August 20 was delayed.
The update is now scheduled for September 5, 2002. A message indicating the
first orbits to be processed after the change will be sent out on September
4. We hope that this change has not created problems for your operations.
Thank you for your patience and cooperation.

***** Following is the original Message sent out on July 24, 2002 with new
date *****
On May 10, 2002, a notice was sent out to the user community announcing
preparations to update the NOAA-15 and 16 HIRS visible coefficients. Test
data is now available on the CEMSCS and anonymous FTP site
(psbsgi1.nesdis.noaa.gov in subdirectory pub\test1b\vicarious). Below is
a list of HIRS 1B test data sets (P1B...) containing NOAA-15/16 HIRS
vicarious coefficients for channel 20 and accompanying GHRR and AMSUA 1B
test data sets as well as corresponding operational data sets (NSS...) that
are available on the anonymous ftp site. This test data will be updated no
more than twice a week unless a request is received for additional data.
Test data on the CEMSCS will run in parallel to the operations.
The changes will go into operations on September 5, 2002.

Below is the new values, current, and prelaunch.
NOAA-15 Vicarious Operation Prelaunch
Slope 0.03174 0.0674 0.02336
Intercept 47.1100 101.0635 36.0500

NOAA-16 Vicarious Operation Prelaunch
Slope 0.02611 0.021354 0.021354
Intercept 62.3307 51.4852 51.4852

From Dr. Cao's notes - "To retrieve the albedo from the HIRS level 1b data,
the following equation should be used:
Albedo = (intercept + slope * C)/cos(z)
Where C is the Earth view count and z is the solar zenith angle for the
pixel. All items are available in the level 1b data."

*Details/Specifics of Change:*
NOAA has established a NOAA-18 operational implementation date of August30, 2005. NOAA-18 will become the primary afternoon satellite in the POES constellation with priority over NOAA-16 in the event of conflicts. Recognizing that some end users are still transitioning to NOAA-18, we will continue to make all NOAA-16 orbital data available. The attached PDF contains information on the constellation change planned for all POES when NOAA-18 becomes operational. This constellation represents the best mix of operational support without jeopardizing the safety and health of our satellites.

POES Constellation Plan

NOAA-18: Primary Operational PM Satellite
All instruments and services are operational. However, the infrared temperature sensor (HIRSl4)
is experiencing an anomaly where channels 1-4 and 12 are out of specifications. The sensor is
considered operational with limitations and the anomaly is under investigation. Per established
NESDIS procedures, the imager channel 3b will be left on to support the fire detection
community. We will process stored global (GAC) and local area (LAC) data and direct readout
(HRPT) data in near-real time. LAC scheduling will start on August 30, 2005

NOM-17: Primary Operational AM Satellite
The microwave temperature instrument has failed. All other instruments and services are
operational. Per established NESDIS procedures, the imager channel 3a will on during day light
conditions to support the snow hydrology community and 3b will be on during night conditions.
We will process stored global (GAC) and local area (LAC) data and direct readout (HRPT) data
in near-real time.

NOAA-16: Back-up Operational PM Satellite
The imager, infrared sounder and ozone instruments are operational with limitations. All other
instruments are operational. All services are operational except APT which has failed. We will
process stored global GAC data but some passes may be delayed due to resource limitations.

NOAA-15: Back-up Operational AM Satellite
The imager, microwave temperature, infrared sounder instruments are operational with
limitations. All other instruments and all services are operational. Since NOAA-17's
microwave temperature sensor failed, we will process stored global (GAC) data in near-real time
on a "best level of effort basis". NOAA-15 will have priority over NOAA-16 if resource
conflicts occur.

NOAA-14: Back-up Operational PM Satellite
The imager is operating with limitations. All other instruments are marginal except the
microwave and stratospheric sounder units which are operational. The search and rescue
processor and APT services have failed. All other services are operational. We will process
non-imagery stored global data, but only download the stored data four or less times a day.
There may be some orbital passes lost due to resource limitations.

NOAA-12: Standby Satellite
The imager and space environmental monitor are operational. All other instruments have failed.
Direct readout services (HRPT and APT) will continue. We will only download stored data once
or twice a day to monitor satellite health. (Note: N-12 does not have a search and rescue
capability.)

*Topic*:
Decommutation change to correct MHS scan line offset and conversion coeffiecients

*Date/Time(UTC) Message Issued:*
29 August 2005, 1645 UTC

*Satellite(s) Involved:*
NOAA-18, but has possibility of affecting all satellites

*Instrument(s) Involved:*
MHS

*Product(s) Involved/Affected:*
MHS

*Date/Time(UTC) of Initial Implementation:*
29 August 2005, Time 1611 UTC

*Details/Specifics of Change:*
On August 29 around 1611 UTC, the level 1B preprocessor was updated to correct MHS problems. This change includes the correction to adjust for the additional scan line offset from AMSU-A data. It also includes a bug fix to properly pass on the NOAA-18 energy conversion coefficients in the header. We expect this to be a no impact change other than improving the data. These updates were necessary in preparation for the switch i n NOAA-18 operational status beginning on August 30.
The first passes to be processed after the change include the following.

NOAA-15 AVHRR Level 1B Data

All,

Please excuse the redundancy of this message. But in order to make this
announcement official it has to be in the correct format with the title of
the authorizing individual.

MEMORANDUM FOR: All NOAA-15 AVHRR Level 1B Data Users

FROM: Barbara Banks
Chief, Information Processing Division

SUBJECT: Discontinuing the Distribution of NOAA-15 Level 1B Data

On November 28th, the Information Processing Division (IPD) will discontinue
the distribution of the NOAA-15 Advanced Very High Resolution Radiometer
(AVHRR) level 1B data. The current AVHRR data produced is not useable and
will no longer be distributed to the general public. The Satellite
Operations Control Center (SOCC) and other offices within the National
Oceanic and Atmospheric Administration (NOAA) will continue efforts to
identify and correct the problem. The user community will be notified when
the AVHRR data is reliable and distribution will resume.

Problems with the AVHRR instrument began in July when the instrument
demonstrated synchronization errors. Since the onboard processor normally
uses the AVHRR to process all other instrument data, this problem rendered
all data unusable. To restore good data for instruments other than AVHRR,
the SOCC switched to using internal synchronization. The spacecraft will be
operated in this mode until a correction to the AVHRR problem is found.
