Subject:
TMP/MWACR/M1 - Snow Buildup
DataStreams:tmpmwacrM1.a1
Description:
There was potentially a build up of snow on the instrument causing large differences in 
the reflectivity as compared with the KAZR.
Measurements:tmpmwacrM1.a1:
  • Spectral Width(spectral_width)
  • Mean Doppler Velocity(mean_doppler_velocity)
  • Reflectivity(reflectivity)

TMP/MWR/M1 - Reprocessing Notice (RID 1250)
DataStreams:tmpmwrlosM1.b1
Description:
See below for details of reprocessing that was completed on 20150607.  Original DQR 
category:4 (Red, Incorrect).

-----------------------------------------------------------

The radiometer was operating with the old calibration coefficients until it had enough tip 
curves to update the calibration. Brightness temperatures are about 3 K lower than 
expected.
Measurements:tmpmwrlosM1.b1:
  • tc31
  • 23.8 GHz sky brightness temperature(tbsky23)
  • Mean 31.4 GHz sky brightness temperature(tbsky31)
  • tc23
  • Water, liquid, total along line-of-sight path(liq)
  • Total water vapor along LOS path(vap)

Subject:
TMP/MWACR/M1 - Possible antenna offset from zenith
DataStreams:tmpmwacrM1.a1
Description:
A preliminary analysis of vertically-pointing Doppler velocity from all four radars at the 
site (KAZR, MWACR, KaSACR and XSACR) suggests that MWACR may have  a systematic velocity 
bias.  The bias appears to depend on height and wind profile,  suggesting it could be 
caused by mispointing of the MWACR.  A more detailed study of the radars plus  sounding 
information indicates the MWACR is mispointed by approximately 1 degree from zenith, into 
azimuth direction of 75 degrees from North.
Measurements:tmpmwacrM1.a1:
  • Spectral Width(spectral_width)
  • Mean Doppler Velocity(mean_doppler_velocity)
  • Reflectivity(reflectivity)
