Subject:
NSA/MWRP/C1 - Hardware failure- Intermittent data
DataStreams:nsamwrpC1.b1
Description:
Data are intermittent during this time due to a failure of the analog board.
The calibration of V-band data may have slightly drifted due to power outages.
Measurements:nsamwrpC1.b1:
  • Derived relative humidity(relativeHumidity)
  • Interpolated dewpoint temperature(dewpointTemperature)
  • air temperature (NGM250 predicted)(temperature)
  • Microwave brightness temperature(brightnessTemperature)
  • Derived virtual temperature(virtualTemperature)

Subject:
NSA/MWRP/C1 - Thermal instability- TKnd test
DataStreams:nsamwrpC1.b1
Description:
During this time the radiometer was thermally unstable . The noise diode physical 
temperature had sudden drops of more than 5 degree in several ccasions between 2/1 and 2/11. On 
2/12 the radiometer temperature set point was lowered of about 10 degree as a test. On 
2/27 a new analog board was installed in the instrument. Data after 2/27 show a slight 
change in calibration.
Measurements:nsamwrpC1.b1:
  • Derived relative humidity(relativeHumidity)
  • Retrieved liquid water path(liquidWaterPath)
  • Retrieved water vapor density(waterVaporDensity)
  • Total precipitable water vapor, from microwave radiometer(totalPrecipitableWater)
  • Retrieved liquid water path using only 23.835 and 30.0 GHz(liquidWaterPath2)
  • air temperature (NGM250 predicted)(temperature)
  • Retrieved total precipitable water vapor using only 23.835 and 30.0 GHz(totalPrecipitableWater2)
  • Microwave brightness temperature(brightnessTemperature)
  • Derived virtual temperature(virtualTemperature)
  • Retrieved cloud liquid water content(liquidWaterContent)
  • Expected root-mean-square error in water vapor density retrieval(waterVaporDensityRmsError)
  • Interpolated water vapor mixing ratio(waterVaporMixingRatio)
