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 - 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. |
