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)
