Subject: | SGP/MWR/B1 - Calibration failure |
DataStreams: | sgpmwrlosB1.b1, sgpmwrtipB1.a1
|
Description: | The radiometer suddenly stopped performing successful tip curve calibrations. Brightness
temperatures are inaccurate during this time. The instrument was removed from service
20071126. Reprocessing is not possible. |
Suggestions: | |
