AWR/KAZR/M1 - Snow Buildup
DataStreams:awrkazrgeM1.a1
Description:
Snow buildup from this system were affecting the sensitivity of the instrument.  Snow was 
cleared on 1/20/16 around 0200 UTC and shows up in the data as a sharp increase in Zh 
values.
Measurements:awrkazrgeM1.a1:
  • Mean doppler velocity, copolar(mean_doppler_velocity_copol)
  • Spectral width, co-polarization(spectral_width_copol)
  • sky_noise_copol
  • signal_to_noise_ratio_copol
  • Reflectivity, co-polarization(reflectivity_copol)

AWR/KAZR/M1 - System Error
DataStreams:awrkazrgeM1.a1
Description:
The TWTA had an error and the radar was not transmitting during this period.  Returns are 
just background noise.
Measurements:awrkazrgeM1.a1:
  • Mean doppler velocity, copolar(mean_doppler_velocity_copol)
  • Spectral width, co-polarization(spectral_width_copol)
  • sky_noise_copol

AWR/KAZR/M1 - Transmit Power Low
DataStreams:awrkazrgeM1.a1
Description:
The data look OK, but the transmit power was reported at ~25dB vs the normal 51dB.  There 
was likely a sensor error with reading the transmitter output, but be cautious when using 
the data either way.
Measurements:awrkazrgeM1.a1:
  • Mean doppler velocity, copolar(mean_doppler_velocity_copol)
  • Spectral width, co-polarization(spectral_width_copol)
  • sky_noise_copol
  • signal_to_noise_ratio_copol
  • rx_noise

AWR/KAZR/M1 - Calibration Constant Shift
DataStreams:awrkazrgeM1.a1
Description:
Calibration constants shifted during this period.  This will likely be corrected in the 
calibration process and provided in b1 level files
