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/WSACR/C1 - Mean Doppler Velocity sign reversed |

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. |
