GRW/MWRP/M1 - Failed LN2 calibration

On 4/28 we tried to perform a LN2 calibration. Because of high humidity and lack of heater 
the calibration was unsuccessful and wrong calibration coefficients were uploaded in the 
configuration file. At 14:10 UTC the old configuration file was reinstated.

GRW/MWRP/M1 - Reprocessed: Updated calibration coefficients

On 9/8/2010 the calibration of of the K-band channels was updated. This caused a slight 
decrease of the retrieved liquid water path. 

Updated calibrations have been applied to data from 7/1-9/8.  The LWP was decreased 
slightly as a result of the recalibration.  Reprocessed data were archived in November 2010.

GRW/MWRP/M1 - Temp/RH sensor failure

The temperature and humidity sensor failed causing software crashes and poor retrieval 
quality.

Surface temperature and humidity are incorrect and the bad temperature readings affected 
the retrievals. Users should completely disregard retrievals from this instrument.
