GRW/MWRP/M1 - Reprocessed: Re-calibration
DataStreams:grwmwrpM1.b1
Description:
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.

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.

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

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

the retrievals. Users should completely disregard retrievals from this instrument.
