NOAA-16 AVHRR channel 3B to 3A Switching >28 July and 01 August, 2003
=============================================================

THE FOLLOWING ACTIONS WILL OCCUR IN ORDER TO MAKE A "SCENE" COMPARISON 
OF AVHRR AND A CALIBRATED RADIOMETER (MODIS).  THE LAC DATA BEING SIMILAR 
TO THE MODIS FOV IS THE REASON FOR THE SWITCH.

Product(s) Involved/Affected:
    AVHRR channel 3B data channel users

Date/Time(UTC) of Initial Implementation:
    28 July 2003, Time 12:56 UTC  Data affected on Rev 14673
    01 August 2003, Time 22:07 UTC  Data affected on Rev 14736

Details/Specifics of Change:
AVHRR channel 3A will be selected on NOAA-16 over part of the polar region. The tests will be 
approx. 5-10 minutes long and encompass the region of 65 degrees north (magnetic) to the peak 
of the orbit (where ascending turns into desending). These two tests are scheduled to occur on 
July 28th, and August 1st of year 2003.
