PGH/MWR/M1 - Reprocess: Incorrect calibration

When the radiometer started to collect data it was not at its final location with 
obstructed field of view. The radiometer was moved to its final location on 7/13/2011. After the 
radiometer was moved it started to collect good data for calibration.

PGH/MWRP/M1 - Reprocessed: Time corrected

The computer clock had the daylight saving on so the measurements time was off 1 hr. The 
setting was changed on 7/15. Data for 20110620-20110715 were time corrected and 
reprocessed.

PGH/MWRP/M1 - Channel interference

The 23.834-GHz channel was displaying high noise levels. It started with intermittent 
noise, but became more persistent with time. The problem was identified as interference from 
the near-by MWR. On 12/7 the radiometers were re-oriented and the noise level went down.
