ENA/MWRP/C1 - Reprocess: Bias in brightness temperatures

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.

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.
