MAO/SONDE/M1 - Reprocessing Notice (RID 1253)
DataStreams:maosondewnpnM1.b1
Description:
See below for details of reprocessing that was completed on 20150121. Original DQR 
category: 4(Red, Incorrect)

-------------------------------------------------------------------------------

The operator incorrectly entered the surface RH value as 10% when it was actually 100%.
Measurements:maosondewnpnM1.b1:
  • Dewpoint Temperature(dp)
  • Humidity, relative, at 21-m height, 30-min avg(rh)

Subject:
MAO/MWRP/M1 - Reprocess: High precipitable water vapor
DataStreams:maomwrpM1.b1
Description:
The precipitable water vapor appears to have a high bias that appears to be due to 
brightness temperatures being calibrated 1.5-2 K too warm. 
The reason for the calibration bias is not known and several attempts at correcting it 
have not been successful. The liquid water path is not affected as much.
Measurements:maomwrpM1.b1:
  • Water vapor, tot. precipitable, from Tbright, 23.835 & 30.0 GHz, stat. retrvl.(totalPrecipitableWater2)
  • Water vapor, total precipitable, derived from Tbright using stat. retrvl.(totalPrecipitableWater)

Subject:
MAO/MWRP/M1 - Sun in the radiometer's field of view
DataStreams:maomwrpM1.b1
Description:
