Subject:	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.

Subject:	NSA/MWRP/C1 - Reprocessed: 6-channel retrieval replaced by 5-channel retrieval
DataStreams:	nsamwrpC1.b1
Description:	Due to repeated failure of the V-band receiver and calibration problems, the 6-channel retrieval was retired and a new 5-channel retrieval which uses only the K-band channels was implemented. All data previously processed with the 6-channel retrieval have been reprocessed. Please note that the 7 channels (brightness temperatures) in the V-band range (51 to 60 GHz) should not be used. See D080331.1 and D080331.2.

Subject:	NSA/MWRP/C1 - V-band noise diode failure
DataStreams:	nsamwrpC1.b1
Description:	The V-band noise diode is showing signs of instability. Starting about August 5 the comparison of brightness temperatures with model showed an increased divergence resulting from a downward trend in the brightness temperatures of frequencies > 50 GHz. Disregard brightness temperatures and retrieved products associated with the V-band channels. These include all profiles. Integrated water vapor and liquid water path are not affected.

Subject:	NSA/MWRP/C1 - Reprocess: Incorrect calibration
DataStreams:	nsamwrpC1.b1
Description:	The calibration of the MWRP drifted starting on September 21. The drift caused a negative LWP. On 10/21 I modified the calibration of the 30 GHz channel in an attempt to correct for the negative bias in LWP. The change in the calibration however caused an excessive increase in the PWV retrievals. The original calibration values were reinstated on 10/29. I then recomputed the temperature coefficients as well as the noise diode injection temperature from tip curves and uploaded the new values on Nov 15 2010.
