First GOES-13 Sounder calibrated radiances

GOES-13
First Sounder Infrared radiances
Data from SSEC Data Center
T. Schmit
ASPB
First GOES-13 Sounder IR – note much less noise
Corresponding GOES-11 Sounder IR – note more noise
Previous GOES-10 Sounder IR – even more noise (eg, ch 15)
Corresponding GOES-11 Sounder IR – less noise than GOES-10
Sounder BAND=1
Due to the different view angles, the same brightness temperature
isn’t expected, but GOES-13 is showing much less noise.
Sounder BAND=15
Due to the different view angles, the same brightness temperature
isn’t expected, but GOES-13 is showing much less noise.
Sounder BAND=15
Improved noise performance of GOES-13 Sounder 4.5 um data
