SGP/KASACR/C1 - Reprocess: Mean Doppler Velocity sign reversed
DataStreams:sgpkasacrvptC1.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:sgpkasacrvptC1.a1:
  • Mean Doppler Velocity(mean_doppler_velocity)

SGP/KASACR/C1 - Transmitter Down
DataStreams:sgpkasacrvptC1.a1
Description:
Transmitter is down during these periods due to a problem with the EIKA.  Data collected 
during this period are bad and do not have any useable returns.
Measurements:sgpkasacrvptC1.a1:
  • Spectral Width(spectral_width)
  • Signal to noise ratio(snr)
  • sky_noise_xpol
  • sky_power_copol
  • cross_polar_differential_phase
  • Reflectivity(reflectivity)
  • Copol to corss-polar correlation coefficient (also known as rhocx)(co_to_crosspol_correlation_coeff)
  • Linear depolarization ratio(linear_depolarization_ratio)
  • Mean Doppler Velocity(mean_doppler_velocity)

DataStreams:sgpkasacrvptC1.a1
Description:
The length and minimum value of range are not stable and change at times.
