PGH/MWRP/M1 - Incorrect retrievals

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.

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.

• time_offset

PGH/MWRP/M1 - Reprocessed: Incorrect V-band calibration

The V-band calibration was incorrect. An LN2 calibration was conducted and the data were 
reprocessed with updated calibrations at the conclusion of the campaign.  The reprocessed 
data were archived in July 2012.

PGH/MWRP/M1 - Reprocessed: Incorrect retrieval coefficients

All retrievals were incorrect because the retrieval coefficients were not available for 
this site. Data were reprocessed at the end of the deployment after the coefficients were 
derived by the mentor.  Reprocessed data were archived in July 2012.

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.

PGH/MWRP/M1 - Incorrect surface temperature and humidity

The surface readings of temperature and humidity are wrong. The sensor needs to be 
replaced. The sensor and dewblower were replaced on Feb 2 2012.

The incorrect surface temperature and humidity will cause wrong retrievals as well.

• Humidity, relative, at instrument height (1 or 2 m)(surfaceRelativeHumidity)
• Density, water vapor, at instrument height (1 or 2 m)(surfaceWaterVaporDensity)
• Temperature, air, at instrument height (1 or 2 m)(surfaceTemperature)
• Pressure, barometric. at instrument height (1 or 2 m)(surfacePressure)
