TMP/XSACR/M1 - Reprocess: Mean Doppler Velocity sign reversed
DataStreams:tmpxsacrvptM1.a1
Description:
The signs of the mean_doppler_velocity field values are incorrect.  The ARM convention for 
this field is that positive velocities indicate motion away from the radar.  However, 
the velocity data in these files have their signs reversed, so that motion TOWARD the radar 
has a positive sign.
Measurements:tmpxsacrvptM1.a1:
  • Mean Doppler Velocity(mean_doppler_velocity)

TMP/XSACR/M1 - Fluctuations in VPT Data
DataStreams:tmpxsacrvptM1.a1
Description:
The KASACR was in continuous vertical point mode during this period.  There are 
fluctuations in the data every hour affecting most variables.
Measurements:tmpxsacrvptM1.a1:
  • Spectral width(spectral_width)
  • Daily values of reflectivity on each grid cell(reflectivity)
  • Copol to cross-polar correlation coefficient (also known as rhocx)(co_to_crosspol_correlation_coeff)
  • Linear depolarization ratio(linear_depolarization_ratio)
  • Signal to noise ratio(snr)
  • Mean Doppler Velocity(mean_doppler_velocity)
  • cross_polar_differential_phase

TMP/XSACR/M1 - Reprocessing Notice (RID 1161)
DataStreams:tmpxsacrvptM1.a1
Description:
See below for details of reprocessing that was completed on 20150706.  Original 
DQR category: 5 (Transparent - Does not affect quality).

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

The field 'linear_depolarization_ratio' is misnamed.  The field should instead be called 
'differential_reflectivity,'
Measurements:tmpxsacrvptM1.a1:
  • Linear depolarization ratio(linear_depolarization_ratio)

Subject:
TMP/XSACR/M1 - Incorrect calibration constant recorded
DataStreams:tmpxsacrvptM1.a1
Description:
Files contain incorrect values for calibration constant(s).  All other fields are correct, 
including reflectivities.   For moments files, the affected fields are called 
'r_calib_radar_constant_h' and 'r_calib_radar_constant_v.'	In spectra files, the global attribute 
'cal_constant' is incorrect.
Measurements:tmpxsacrvptM1.a1:
  • r_calib_radar_constant_v
  • r_calib_radar_constant_h
