Subject: | FKB/WACR/M1 - Decreased Pulse Repetition Frequency |
DataStreams: | fkbwacrM1.b1 |
Description: | Following a disk swap, an old configuration file was used, which set the Pulse Repetition Frequency to 8333 Hz instead of the intended 10000 Hz. This caused Nyquist velocity to be reduced to 6.57 m/s (from 7.885 m/s) and the maximum height of data collection to increase to 18215 m MSL (from 15215 m MSL). |

Subject: | FKB/WACR/M1 - No cross polar data collected |
DataStreams: | fkbwacrM1.b1 |
Description: | Following a disk swap, the wrong configuration file was used. As a result only co-polar data was collected. No cross polar data is available for this period. Also, the maximum height of data collection was 7672 m MSL. |

Subject: | FKB/WACR/M1 - Radar parameters changing frequently |
DataStreams: | fkbwacrM1.b1 |
Description: | The number of data heights and polarization status changed several times during this brief period. Look at each data file during this period to determine the number of heights of data collection and whether dual polarization data or only co-polar data was collected. (pol_mode = 0 for co-polar only, pol_mode = 2 for alternating co-polar/cross-polar data collection). |

Subject: | FKB/WACR/M1 - Reflectivity and Height Offsets |
DataStreams: | fkbwacrM1.b1, fkbwacrspeccmaskxpolM1.a0, fkbwacrspeccmaskcopolM1.a0 |
Description: | The instrument vendor has informed us of a range (height) offset of 13 m and has provided an updated reflectivity calibration. All values reported for 'Reflectivity' are approximately 1.5 dB too low. In addition, the Reflectivity in the first and fourth range gates (starting from the surface) need to be further corrected by an additional 2.7 and -0.9 dB, respectively. The 'height' field values are 13.33 m too low. The data will be reprocessed to correct these problems. |
