GOES-13 First 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

Due to the different view angles, the same brightness temperature isn’t expected, but GOES-13 is showing much less noise. 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

First IR Imager images – preliminary – not calibrated. In general way too cold.
