Topic: NOAA-15 and NOAA-19 AVHRR Channel 3A / 3B Switching Deactivation over Alaska Region
Date/Time Issued: May 10, 2018 1750Z
Product(s) or Data Impacted: NOAA-15 and NOAA-19 AVHRR data over Alaska Region
Date/Time of Initial Impact: May 14, 2018 00:02:51Z
Date/Time of Expected End: Seasonally (Ongoing)
Length of Outage: See details below; roughly 4 months
Details/Specifics of Change: NESDIS Office of Satellite and Product Operations (OSPO) engineers will deactivate switching for NOAA-15 and NOAA-19 AVHRR Channel 3A / 3B for the period of May 14, 2018 to September 15, 2018. Switching to Channel 3A will not occur during this period over the predefined box encompassing the Alaska Region (box coordinates 50M-0N to 75M-0N and 173M-0E to 135M-0W). NOAA-15 and NOAA-19 AVHRR will remain Channel 3B (3.7 microns) to support fire detection and monitoring activities over Alaska Region.
Last NOAA-15 contact 15 F 4027 May 14, 2018 134/19:24:50 134/19:32:31 461
Last NOAA-19 contact 19 F 47749 May 14, 2018 134/23:54:10 134/23:59:03 293
Channel switching will stop after May 14, 2018 for the beginning of fire season.
The coordination for the activation and deactivation of switching for NOAA-15 and NOAA-19 AVHRR Channel 3A / 3B is a collaborative effort between NESDIS OSPO, National Weather Service (NWS) Alaska Region, University of Alaska - Geographic Information Network of Alaska (GINA), and the NWS Fire Weather Service Manager and is intended to seasonally optimize the Fire Weather and Cryosphere observing posture for Alaska.
