Subject:	NSA/KAZR/C1 - PLO Failure
DataStreams:	nsakazrgeC1.a1
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.

Subject:	NSA/KAZR/C1 - Reprocessing Notice (RID 836 )
DataStreams:	nsakazrgeC1.a1
Description:	See below for details of reprocessing that was completed on 20141223. Original DQR category: 4 (Red, Incorrect) ----------------------------------------------------------------------------- The calibration constants for the modes were incorrect. The coefficients used were BL: -34.70 dB GE: -18.69 dB The correct coefficients are BL: -22.21dB GE: -13.14 dB
Measurements:	nsakazrgeC1.a1: cal_constant_xpol Reflectivity, cross-polarization(reflectivity_xpol) Reflectivity, co-polarization(reflectivity_copol) cal_constant_copol

Subject:	NSA/KAZR/C1 - Reprocess: Incorrect calibration coefficients
DataStreams:	nsakazrgeC1.a1
Description:	reflectivity between long and short pulse did not agree with each other after analyzing data. Data will be reprocessed.
Measurements:	nsakazrgeC1.a1: Reflectivity, cross-polarization(reflectivity_xpol) Reflectivity, co-polarization(reflectivity_copol)

12/14/2012	1650	03/17/2013	1835	Suspect

Subject:	NSA/KAZR/C1 - Shift in Background Reflectivity and Signal-to-Noise Ratio
DataStreams:	nsakazrgeC1.a1
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:	nsakazrgeC1.a1: signal_to_noise_ratio_xpol signal_to_noise_ratio_copol Reflectivity, cross-polarization(reflectivity_xpol) Reflectivity, co-polarization(reflectivity_copol)
