*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.
