Topic:

Corrections made to software processing dynamice test data

Date/Time(UTC) Message Issued:
14 march 2005 14:45 UTC

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

Instrument(s) Involved:
AVHRR and HIRS

Product(s) Involved/Affected:
NONE...test data only

Date/Time(UTC) of Initial Implementation:
11 March 2005 14:45 UTC

Details/Specifics of Change:

On March 10 and 11, two problems were corrected. For the Advanced Very
High Resolution Radiometer (AVHRR), the calibration algorithm was updated to
change the acceptance limit for PRT data. This corrected the problem of PRT
values not being used in the calibration and resulted in flags set to match
current operations. For the High Resolution Infrared Radiation Sounder
(HIRS), software for the level 1B format was updated to store the
channel quality flags in the proper order. The flags were being stored in
ascending channel order rather than telemetry order as specified in the
format.

The HIRS update was implemented the evening of March 10.

The AVHRR change was implemented on March 11 around 14:45 UTC beginning
with the following passes:

NOAA-15 B3548586
NOAA-16 B2302930
NOAA-17 B1409697
