SUBJECT GOES-10 SOUNDER BIAS MODE CHANGE
THE FOLLOWING INFORMATION WAS RECEIVED TODAY FROM SOCC.

STEVE.ARNETT/AT SYMBOL/NOAA.GOV
ON MONDAY... FEBRUARY 22... 1999... AT APPROXIMATELY 1550 GMT...
NOAA ENGINEERS WILL CHANGE THE BIAS MODE USED IN THE
GOES-10 SOUNDER CALIBRATION PROCESS... TO HELP MINIMIZE DRIFT
IN THE BIAS FACTORS /INTERCEPTS/ BETWEEN SPACE LOOKS. BIAS
MODE 2 WILL ALLOW THE BIAS TO BE CALCULATED MORE
FREQUENTLY... AND ESTIMATED BASED ON ITS CORRELATION
WITH THE VARIATION IN OPTICS TEMPERATURE. DURING CERTAIN
PARTS OF THE DAY WHEN OPTICS TEMPERATURES ARE
CHANGING RAPIDLY... THIS MODE PROVIDES A BETTER CORRELATION
BETWEEN BIAS VARIATION AND OPTICS TEMPERATURE... AND WILL
ULTIMATELY PROVIDE FOR A HIGHER-QUALITY SOUNDING.
