NSA/MWRP/C1 - Reprocessed: K-Band calibration drift
DataStreams:nsamwrpC1.b1
Description:
At the beginning of November, the K-band channel calibration started to drift. The MWRP 
brightness temperatures were about 1.5 K higher than the MWR-measured brightness 
temperatures. By the half of the month the differences were more than 2 K to become about 4 K by 
the end of November. On Nov 27 new calibration coefficients were derived and uploaded.

Data for 20061101-20061127 have been reprocessed with the revised calibrations and are 
available from the ARM Archive effective January 2007.
Suggestions: 
Retrieve reprocessed data for use in data analysis.
