*Update#2: *This operation was not performed yesterday due to
unavailability of resources at Wallops and will be executed today
December 4, 2014*.
Correction Update #1: *This operation will be performed Wednesday,
December 3, 2014 2100 UTC*
Update#1 *This operation will be postponed until further notice due to
critical weather today.*
Topic: *GOES-15 (GOES-West) Sounder East-West scan mirror emissivity
coefficients will be updated on December 4, 2014.
*Date/Time Issued:* December 4, 2014 1430 UTC
*Product(s) or Data Impacted:* GOES-15 (GOES-West) Sounder GVAR Data
*
**Date/Time of Initial Impact:* December 4, 2014 2100 UTC
*
**Date/Time of Expected End: * Permanent Change
*
**Length of Outage:* N/A
*
**Details/Specifics of Change:*
On Thursday, December 4, 2014, the new scan mirror emissivity
coefficients for GOES-15 Sounder will be promoted to the GOES
Operations
during housekeeping at 2045 UTC.
The existing GOES-15 (GOES-West) Sounder East-West emissivity
coefficients in use since GOES-15 Post Launch Test have been in slight
error, and the new emissivity coefficients delivered by the instrument
vendor will correct these errors. Upon this changeover users can expect
to see small improvement in accuracy of the GOES-15 (GOES-West) Sounder
calibrated radiances, most noticeably on channel 8 (11 um band). The
improvement is not uniform, and will depend on both the detected Earth
scene temperature and the time-of-day (via the diurnally varying
temperature of the Sounder scan mirror).
