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 switch
between Channel 3B
and Channel 3A to support snow and ice detection and
monitoring activities over
Alaska Region.

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.
