| Subject: | FKB/WACR/M1 - No cross polar data collected |
|---|---|
| Affected 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 - Chaff released in Murg valley |
|---|---|
| Affected Datastreams: | fkbwacrM1.b1 |
| Description | As part of the research activities associated with the COPS field campaign, the research center at Karlsruhe released aluminum chaff (2.5 cm in length) in the Murg Valley in order to study atmospheric diffusion. It is possible that some of this chaff drifted over the AMF site and thus may have influenced the radar observations (as spurious echos). 20070817 Comment from WACR Mentor, Kevin Widener: I reviewed the data from the two chaff releases and I'm unable to see any effect in either co-polar or cross-polar backscatter signals. I also looked at the MPL and ceilometer and could not see anything that might be chaff. {Editors note: The DQR quality color was changed to "Transparent".} |

| Subject: | FKB/WACR/M1 - Decreased Pulse Repetition Frequency |
|---|---|
| Affected 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 - Radar parameters changing frequently |
|---|---|
| Affected 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: | HFE/WACR/M1 - Reprocessed: Reflectivity and Height Offsets |
|---|---|
| Affected Datastreams: | hfewacrspeccmaskxpolM1.a0 |
| Description | The instrument vendor informed us of a range (height) offset of 13 m and provided updated reflectivity calibration. All values reported for 'Reflectivity' were approximately 3 dB too low. In addition, the Reflectivity in the first and fourth range gates (starting from the surface) needed to be further corrected by an additional 2.7 and -0.9 dB, respectively. The 'height' field values were 13.33 m too low. The data were reprocessed to correct these problems. The hfewacrM1.b1 data were reprocessed and archived in October 2010. The hfewacrspeccmaskcopolM1.a0 and hfewacrspeccmaskxpolM1.a0 data were reprocessed and archived in January and July 2012. |
