After the new dewblower was installed there was a shift in the calibration of the 
instrument. The instrument was calibrated on 8/29. Data between 8/19 and 8/29 have been 
reprocessed to apply the new calibrations.  Reprocessed data were archived in December 2009.

GRW/MWRP/M1 - Failed LN2 calibration
DataStreams:grwmwrpM1.b1
Description:
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.

Subject:
GRW/MWRP/M1 - Reprocessed: Updated calibration coefficients
DataStreams:grwmwrpM1.b1
Description:
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.

  • Water vapor, tot. precipitable, from Tbright, 23.835 & 30.0 GHz, stat. retrvl.(totalPrecipitableWater2)

GRW/MWRP/M1 - Temp/RH sensor failure
DataStreams:grwmwrpM1.b1
Description:
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.
