The PreProduct Processing group has plans to implement the following
changes within the level 1B/1B* data before the freeze scheduled for
around the December 17th time frame. We are requesting feedback from
the instrument scientists on the differences that the users will see due
to the planck constant update, as soon as possible. This information
will be passed on to the user community. Initial 1B test data has been
provided on the anonymous ftp site along with ops data
(psbsgi1.nesdis.noaa.gov under subdirectory pub/test1b/R2.9A) as
indicated at the end of this message. CEMSCS data users will find 1B*
data under the P1S data set names and 1B data under P1B data set names.
1. Correction of the Planck contants in response to the request from
the Satellite Products and Services Review Board to adopt the 1998
CODATA constants for all operational systems in
NESDIS.
Current Planck constants: c1 = 0.119104398E-04 c2 =
1.43876934
1998 CODATA constants: c1 = 0.119104270E-04 c2 =
1.43877506
2. Orbit Parameters in the Header - Under certain circumstances we may
be required by the Air Force to discontinue distribution of the orbit
parameters in header for a period of time. To meet any such future
requests, we are introducing a capability to zero out the orbit
parameters (epoch date, time, and 12 orbit parameters) by toggling them
on and off. (This change will also impact NOAA-12 and NOAA-14. Test
data will be provided.)
Normal parallel test runs will begin on Monday, November 26th, with the
orbit parameters provided as normal. After one week the orbit
parameters will be turned off for a week (beginning Monday, December
3rd) and then back on the following week (Monday, December 10th).
Please contact Arlington Morgan (Arlington.Morgan@noaa.gov or
301-457-5262) or Emily Harrod (Emily.Harrod@noaa.gov or 301-457-5247) if
you have any questions or problems.
Thank you
