Subject:
NIM/MWRP/M1 - 51.25 GHz channel calibration drifted
DataStreams:nimmwrpM1.b1
Description:
After a power outage on May 5 the 51.25 GHz had a slight change in the calibration. The 
resulting LWP computed by using all 6 channels increased of about 0.025 mm (25 g/m2).
Measurements:nimmwrpM1.b1:
  • Microwave brightness temperature(brightnessTemperature)

Subject:
NIM/MWRP/M1 - Reprocessed: K-band calibration drift corrected
DataStreams:nimmwrpM1.b1
Description:
During October and November there was a drift in the K-Band calibration of the MWRP. This 
resulted in brightness temperatures that were too high.

New calibration coefficients were derived from the median value of the noise diode 
temperature for the months of October and November and the data were reprocessed to apply the 
corrected calibrations.  The reprocessed data were archived in January 2007.
