Subject: NSA/KAZR/C1 - Reprocess: Incorrect calibration coefficients
Affected Datastreams: nsakazrspeccmaskgexpolC1.a0
Description The wrong calibrations were used due to a problem with the software. Mentor discovered the reflectivity between long and short pulse did not agree with each other after analyzing data. Data will be reprocessed.
Measurements
  • reflectivity (Reflectivity)

Subject: NSA/KAZR/C1 - PLO Failure
Affected Datastreams: nsakazrspeccmaskmdcopolC1.a0
Description Streaks began showing up in radar data (reflectivity, doppler velocity, spectral width, SNR) at semi regular intervals. Problem was a failed 16.560 GHz Phase Lock Oscillator (PLO). PLO was replaced 20120214.
Measurements
  • spectral_width (Spectral Width)
  • reflectivity (Reflectivity)
  • mean_doppler_velocity (Mean Doppler Velocity)
  • base_time (Base time in Epoch)
  • time_offset (Time offset from base_time)
  • time (Time offset from midnight)
  • alt (Altitude above mean sea level)
  • lat (North latitude)
  • lon (East longitude)
  • signal_to_noise_ratio (Signal-to-noise ratio)

Subject: NSA/KAZR/C1 - Shift in Background Reflectivity and Signal-to-Noise Ratio
Affected Datastreams: nsakazrspeccmaskgexpolC1.a0
Description The KAZR experienced an abrupt shift in the background reflectivity on 12/14/2012, followed by a shift in the background Signal-to-Noise Ratio on 12/16/2012. The background levels then revert back to "normal" levels on 3/17/2013. Cause is currently unknown.
Measurements
  • reflectivity (Reflectivity)
  • signal_to_noise_ratio (Signal-to-noise ratio)
