Subject:
TWP/MWR3C/C3 - Incorrect calibration
DataStreams:twpmwr3cC3.b1
Description:
When the radiometer was relocated to the TWP site the 89-GHz detector non-linearity 
coefficient got somehow erased from the radiometer memory. The radiometer was therefore unable 
to calibrate properly.
Measurements:twpmwr3cC3.b1:
  • Radiation, longwave, brightness temperature, 23.8 GHz(tbsky23)
  • 89.0 GHz sky brightness temperature(tbsky89)
  • Water vapor, precipitable, column-integrated on isobaric grid, from RUC model(pwv)
  • Liquid water path best-estimate value, hourly mean(lwp)
  • 30.0 GHz sky brightness temperature(tbsky30)

Subject:
TWP/MPL/C1 - Polarization failure
DataStreams:twpmplpolfsC1.b1
Description:
MPLPOL polarization began to fail with cross_pol and co_pol modes both returning identical 
scatter.  Instrument replaced 20120502
Measurements:twpmplpolfsC1.b1:
  • Attenuated backscatter, cross pol(signal_return_cross_pol)
  • background_signal_std_cross_pol
  • background_signal_cross_pol
