PGH/MWRP/M1 - Incorrect retrievals
DataStreams:pghmwrpM1.b1
Description:
Retrievals from this instrument are affected by the wrong surface temperature and humidity 
readings. Retrievals are wrong until 2/2/2012 when the dewblower was replaced.
Suggestions: 
Measurements:pghmwrpM1.b1:
  • Expected root-mean-square error in liquid water content retrieval(liquidWaterContentRmsError)
  • Retrieved total precipitable water vapor using only 23.835 and 30.0 GHz(totalPrecipitableWater2)
  • Lifting condensation level(liftingCondensationLevel)
  • Retrieved water vapor density(waterVaporDensity)
  • Derived virtual temperature(virtualTemperature)
  • Expected root-mean-square error in liquid water path retrieval using only 23.835
