Subject: | NSA/MWRP/C1 - Radiometer in mixed scanning-zenith mode |
DataStreams: | nsamwrpC1.b1
|
Description: | After installing the spare radiometer (D080409.2), the data started to be intermittent and
the software froze several times. To test if the problem was due to the scanning
procedure used with the other radiometer, the instrument was run with a zenith-only procedure at
times and with the usual scanning procedure at restart. When restarted with the scanning
procedure the software had problems, so it was decided to run the spare instrument only
with the zenith-viewing mode until our instrument comes back.
The quality of the data should be unaffected. The only difference is that only data
collected at 90 degree angle will be available until our instrument comes back. |

Subject: | NSA/MWRP/C1 - Reprocess: LN2 calibration |
DataStreams: | nsamwrpC1.b1
|
Description: | On 4/9 a spare radiometer was installed at the site. On 4/18 a LN2 calibration was
conducted. Upon examination of the data it appeared that the LN2 calibration was generally
successful, however the 30-GHz channel was not calibrated properly.
New calibration coefficients for all K-band channels were derived and data for the whole
month should be reprocessed with these newly derived coefficients. I will provide the new
configuration file.
An explanation of the effects of the poor calibration is given in the Instrument Mentor
Monthly Summary report. The poor calibration affected the LWP in particular. Re-calibration
will correct the problem. |

|
Description: | Reflectivity dBZ values should not be used. The reported cloud boundaries may
underestimate cloud tops, particularly for high or thick clouds. Also thin high clouds may have
been missed entirely, especially if there were lower-level cloud layers below them. During
this time period, the MMCR was transmitting in circular polarization, rather than
(correct) linear polarization. This caused reported Reflectivity values to be too low by an
unknown amount, resulting in an effective loss of radar sensitivity.
Areas identified as have having hydrometeor detections are correct, however some areas
marked as clear may in fact contain cloud due to the MMCR's low sensitivity during this time. |
