Subject: Administrative, Update #1: NOAA-19 AVHRR Channel 3A / --001a113ef9fcecee3b052ffea4ed Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Update #1: The AVHRR channel 3A/3B channel switching activation over the Alaska region on NOAA-19 will begin on jday 103 (16/103, 4/12/2016) at 01:24:20 UTC on Rev 36981 and last until the middle of May when the fire season begins in the AK region. Of the 14 passes scheduled daily for NOAA-19, 6 to 7 passes will be at Fairbanks with about 4 to 5 of these in the AK box for 3 minutes or longer. Topic: NOAA-19 AVHRR Channel 3A / 3B Channel Switching Activation over Alaska Region Date/Time Issued: April 8, 2016 2000 UTC Product(s) or Data Impacted: NOAA-19 AVHRR data over Alaska Region Date/Time of Initial Impact: April 12, 2016 0124 UTC Date/Time of Expected End: Seasonally (Ongoing) Length of Outage: See details in table Details/Specifics of Change: Office of Satellite and Product Operations (OSPO) engineers will activate channel switching for NOAA-19 AVHRR Channel 3A / 3B on April 12, 2016 within a predefined box encompassing the Alaska Region only (box coordinates 50=C2=B0N to 75=C2=B0N and 173=C2=B0E to 135= =C2=B0W). Switching to NOAA-19 AVHRR Channel 3A (1.6 microns) over this area will further support the Alaska Region=E2=80=99s Snow and Ice Mission by providing impro= ved snow and ice discrimination. No switching will occur during the summer fire season annually from the period of May 15th to September 15th as NOAA-19 AVHRR will remain Channel 3B (3.7 microns), which traditionally supports fire detection. This change is being made in coordination with the 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. Please Note: For scheduling and product generation purposes, channel switching will not be activated for satellite passes that are within the predefined box for less than three minutes. This is a follow-on to the activation of channel switching for NOAA-15 AVHRR Channel 3A / 3B which was executed back on March 2, 2016.
