NSA/MWRP/C1 - Reprocessed: K-Band calibration drift
DataStreams:nsamwrpC1.b1
Description:
At the beginning of November, the K-band channel calibration started to drift. The MWRP 
brightness temperatures were about 1.5 K higher than the MWR-measured brightness 
temperatures. By the half of the month the differences were more than 2 K to become about 4 K by 
the end of November. On Nov 27 new calibration coefficients were derived and uploaded.

Data for 20061101-20061127 have been reprocessed with the revised calibrations and are 
available from the ARM Archive effective January 2007.
Measurements:nsamwrpC1.b1:
  • Lifting condensation level pressure(liftingCondensationLevelPres)
  • Derived relative humidity(relativeHumidity)
  • Retrieved liquid water path(liquidWaterPath)
  • Level of free convection pressure(levelFreeConvectionPres)
  • Retrieved water vapor density(waterVaporDensity)
  • Retrieved liquid water path using only 23.835 and 30.0 GHz(liquidWaterPath2)
  • Retrieved total precipitable water vapor using only 23.835 and 30.0 GHz(totalPrecipitableWater2)
  • Convective Available Potential Energy(cape)
  • Microwave brightness temperature(brightnessTemperature)
  • Lifting condensation level(liftingCondensationLevel)
  • Level of free convection(levelFreeConvection)
  • Interpolated dewpoint temperature(dewpointTemperature)
  • Total precipitable water vapor, from microwave radiometer(totalPrecipitableWater)
  • Retrieved cloud liquid water content(liquidWaterContent)
  • Interpolated water vapor mixing ratio(waterVaporMixingRatio)
