Topic: GOES-12 (GOES-South America) Imager/Sounder Patch Temperature
Change
is scheduled for March 30, 2012
Date/Time Issued: March 29, 2012 1610 UTC
Product(s) or Data Impacted: no immediate effect to products other than
unnoticeably higher noise levels due to higher IR detector temperatures
at
this setting.
Date/Time of Initial Impact: March 30, 2012 0315 UTC
Date/Time of Expected End: See details.
Length of Outage: N/A
Details/Specifics of Change: On March 30, 2012 (DOY 90), engineers will
change the GOES-12 (GOES-South America) Imager and Sounder patch
temperatures from their LOW set points (90.9 K and 88.5 K respectively)
to
their MID set-points (98.9 K and 98.3 K) at about 0315 UTC. The
change will
be done during keep out zone (KOZ) time and prior to eclipse to
minimize
the impact on users. The temperature transition will take approximately
1
hour during eclipse and is not expected to effect products other than
unnoticeably higher noise levels due to higher IR detector temperatures
until the next change down in Fall. The patch will be controlled
at this
temperature (98.9 K and 98.3 K) until September 2012 when it will be
switched back to LOW settings during fall eclipse/KOZ season.
MBCC (Midnight Blackbody Calibration Correction) will also be
turned off
for the Imager at the time of the patch temp change and will be
turned back
on approximately two days later.
