1. GOES-13 First Infrared radiances Data from SSEC Data Center T. Schmit ASPB

2. First GOES-13 Sounder IR – note much less noise

3. Corresponding GOES-11 Sounder IR – note more noise

4. Previous GOES-10 Sounder IR – even more noise (eg, ch 15)

5. Corresponding GOES-11 Sounder IR – less noise than GOES-10

6. Due to the different view angles, the same brightness temperature isn’t expected, but GOES-13 is showing much less noise. Sounder BAND=1

7. Due to the different view angles, the same brightness temperature isn’t expected, but GOES-13 is showing much less noise. Sounder BAND=15

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

9. Corresponding GOES-12 Imager
