Subject:
ENA/MWRP/C1 - Reprocess: Bias in brightness temperatures
DataStreams:enamwrpC1.b1
Description:
The brightness temperatures between 22.234 and 26.234 GHz show a bias of 1.7 to 3.6 
degrees K. Data needs to be recalibrated. As a consequence the retrieved precipitable water 
vapor has a positive bias.
Measurements:enamwrpC1.b1:
  • Water vapor, tot. precipitable, from Tbright, 23.835 & 30.0 GHz, stat. retrvl.(totalPrecipitableWater2)
  • Microwave brightness temperature(brightnessTemperature)
  • Liquid water path, from Tbright at 23.835 and 30.0 GHz only, using stat. retrvl.(liquidWaterPath2)
  • Liquid water path, from brightness temperatures using statistical retrieval(liquidWaterPath)

ENA/MWRP/C1 - Reprocessing Notice (RID 1261)
DataStreams:enamwrpC1.b1
Description:
See below for details of reprocessing that was completed on 20150309.  Original DQR 
category: 3 (Yellow, Suspect).

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

The radiometer's calibration appears unstable. The brightness temperatures are warmer than 
expected. Data need to be recalibrated.
Measurements:enamwrpC1.b1:
  • Water vapor, tot. precipitable, from Tbright, 23.835 & 30.0 GHz, stat. retrvl.(totalPrecipitableWater2)
  • Microwave brightness temperature(brightnessTemperature)
  • Liquid water path, from Tbright at 23.835 and 30.0 GHz only, using stat. retrvl.(liquidWaterPath2)
  • Liquid water path, from brightness temperatures using statistical retrieval(liquidWaterPath)
  • Water vapor, total precipitable, derived from Tbright using stat. retrvl.(totalPrecipitableWater)

Subject:
ENA/MWRP/C1 - Reprocess: Calibration drift
DataStreams:enamwrpC1.b1
Description:
The data are incorrect mostly because of fast drift in the calibration. Brightness 
temperatures become negative after 9/7/2015.
Measurements:enamwrpC1.b1:
