Subject: | NSA/MWRP/C1 - Spare radiometer installed |
DataStreams: | nsamwrpC1.00, nsamwrpC1.b1, nsamwrprawC1.00 |
Description: | A spare radiometer was provided by Radiometrics while they try to fix our MWRP. The spare radiometer is of the same family as the one we have in Barrow and it will stay at the site until our radiometer is repaired. A LN2 calibration will be performed next week. |

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. |

DataStreams: | nsamwrpC1.00, nsamwrpC1.b1, nsamwrprawC1.00 |
Description: | A spare radiometer was installed a the site to substitute the malfunctioning radiometer (see DQRs D080409.2 and D080421.1). During this time the spare radiometer had problems starting and was stopping collection suddenly. Data during this time are very intermittent with large gaps. |

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. |

Subject: | NSA/MWRP/C1 - Increased RF intereference |
DataStreams: | nsamwrpC1.b1 |
Description: | The spare radiometer experienced increased levels of RF interference. The interference is prominent on the 30-GHz channel and LWP retrievals that appear particularly noisy. |
