NSA/MWRP/C1 - Incorrect surface measurements
DataStreams:nsamwrpC1.b1
Description:
Surface measurements are spiking and not comparing well with the co-located METTWR 
measurements.

On 2/13 site operators cleaned a filter in the heater housing resolving the problem.
Measurements:nsamwrpC1.b1:
  • Surface pressure at instrument(surfacePressure)
  • Surface water vapor density at instrument(surfaceWaterVaporDensity)
  • Surface absolute temperature at instrument(surfaceTemperature)
  • Surface relative humidity at instrument(surfaceRelativeHumidity)

Subject:
NSA/MWRP/C1 - Incorrect surface measurements
DataStreams:nsamwrpC1.b1
Description:
The MWRP surface temperature and pressure readings were in disagreement with those from 
other instruments. The possible cause of the disagreement was ice buildup around the 
sensors.  Readings returned to normal March 29.

The temperature readings were more affected. Since the readings are erratic, with large 
oscillations, it is not possible to correct them. Disregard the surface temperature and 
humidity readings during this time. The wrong readings will affect the first layer of the 
temperature and humidity profiles as well.
Measurements:nsamwrpC1.b1:
  • Surface pressure at instrument(surfacePressure)
  • Surface water vapor density at instrument(surfaceWaterVaporDensity)
  • Surface absolute temperature at instrument(surfaceTemperature)
  • Surface relative humidity at instrument(surfaceRelativeHumidity)

Subject:
NSA/MWRP/C1 - Reprocessed: 6-channel retrieval replaced by 5-channel retrieval
DataStreams:nsamwrpC1.b1
Description:
Due to repeated failure of the V-band receiver and calibration problems, the 6-channel 
retrieval was retired and a new 5-channel retrieval which uses only the K-band channels was 
implemented.

All data previously processed with the 6-channel retrieval have been reprocessed.
Measurements:nsamwrpC1.b1:
  • Retrieved liquid water path(liquidWaterPath)
  • Retrieved liquid water path using only 23.835 and 30.0 GHz(liquidWaterPath2)
  • Microwave brightness temperature(brightnessTemperature)
