Subject: Administrative: GOES-15 (GOES-West) Sounder IR Detector Patch This is a multi-part message in MIME format. --Boundary_(ID_fOzYo7qcomiJkGEUMSIo5A) Content-type: text/plain; charset=UTF-8; format=flowed Content-transfer-encoding: 7BIT *Topic*: GOES-15 (GOES-West) Sounder IR Detector Patch Temperature Change *Date/Time Issued*: April 2, 2015 1605 UTC *Product(s) or Data Impacted*: GOES-15 (GOES-West) Sounder Data *Date/Time of Initial Impact*: April 8, 2015, at approximately 0822 UTC *Date/Time of Expected End*: April 8, 2015, at approximately 1120 UTC *Length of Outage*: approx. 3 hours * Details/Specifics of Change*:**On April 8, 2015, SOCC Engineers will change the GOES-15 Sounder patch temperature from its HIGH set point (88 K) to its LOW set-point (82 K) starting around 0822 UTC (4:22 am EDT) just prior to space craft eclipse (sounder outage). The temperature transition will take approximately 3 hours. Most of the temperature transition will happen during the 08:22-10:01 sounder outage due to stray light contamination around the space craft eclipse. However, the next three images (10:01 CONUS, 10:24 Hawaii, and 11:01 CONUS) may be effected by striping/banding until the temperature is stabilized at its new setting around 1100 UTC. GOES-15 patch changes are necessary to minimize temperature fluctuations around each equinox due to the cooler blanket anomaly and Yaw Flip operations. The signal to noise ratio and responsivity will improve as a result of operation at a lower patch (detector) temperature.
