ENA/MWRP/C1 - Bad calibration
DataStreams:enamwrpC1.b1
Description:
The radiometer was poorly calibrated following a power outage at the site.

  • Temperature, virtual, vert. prof. sfc-10km, fr. wtr. vap. dens. and temp. prof.(virtualTemperature)
  • Microwave brightness temperature(brightnessTemperature)
  • Temperature at the ground station(temperature)
  • Height, level of free convection(levelFreeConvection)
  • Density, water vapor, prof. from sfc.-10 km, der. from Tbright stat. retrvl.(waterVaporDensity)

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)
  • 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:
  • Water vapor, tot. precipitable, from Tbright, 23.835 & 30.0 GHz, stat. retrvl.(totalPrecipitableWater2)
  • Microwave brightness temperature(brightnessTemperature)

  • Mixing ratio, water vap., vert. prof. sfc-10km, frm retr. water vap. dens. prof(waterVaporMixingRatio)
  • 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)

Subject:
ENA/MWRP/C1 - Occasional outages of surface T/RH readings
DataStreams:enamwrpC1.b1
Description:
Occasionally the surface temperature and relative humidity readings are not updated and 
the measurements appear flat for short times. The primary data are most likely not affected 
because the surface measurements are flatlined for short intervals when big changes are 
not expected.
Measurements:enamwrpC1.b1:
  • Pressure, barometric. at instrument height (1 or 2 m)(surfacePressure)
  • Temperature, air, at instrument height (1 or 2 m)(surfaceTemperature)
  • Humidity, relative, at instrument height (1 or 2 m)(surfaceRelativeHumidity)
  • Density, water vapor, at instrument height (1 or 2 m)(surfaceWaterVaporDensity)
