Subject: | GRW/MWRP/M1 - Reprocessed: Updated calibration coefficients |
DataStreams: | grwmwrpM1.b1 |
Description: | On 5/15 the K-band calibrations were updated with coefficients derived from tip curves. The 20090501-20090515 data were reprocessed to apply the updated calibration coefficients. |

Subject: | GRW/SONDE/M1 - Wind data missing |
DataStreams: | grwsondewnpnM1.b1 |
Description: | A GPS problem associated with Vaisala BBSS ground station software issues caused the ground stations to enter into an error state when using GPS wind finding. In some instances, the flight was aborted due to the error state and no data was collected. A workaround was developed to allow sondes to be launched without collecting wind data. |

Subject: | GRW/MWRP/M1 - Reprocessed: Re-calibration |
DataStreams: | grwmwrpM1.b1 |
Description: | After the new dewblower was installed there was a shift in the calibration of the instrument. The instrument was calibrated on 8/29. Data between 8/19 and 8/29 have been reprocessed to apply the new calibrations. Reprocessed data were archived in December 2009. |

Description: | Data are suspect. There is a discrepancy between the 1640 channel and the other channels. The discrepancy is possibly related to the intermittent obstruction (a lizard) found in the collimator tube. There may also be ongoing degradation of the instrument possibly related to the lizard activity and deposits. |

Description: | There were problems with the almucantar scans causing difficulty in tracking the sun between the almucantar scans for each wavelength. The instrument was due for calibration and maintenance. This unit was replaced on 5/6/2010. |

Subject: | GRW/MWRP/M1 - Failed LN2 calibration |
DataStreams: | grwmwrpM1.b1 |
Description: | On 4/28 we tried to perform a LN2 calibration. Because of high humidity and lack of heater the calibration was unsuccessful and wrong calibration coefficients were uploaded in the configuration file. At 14:10 UTC the old configuration file was reinstated. |

DataStreams: | grwmwrpM1.b1 |
Description: | On 9/8/2010 the calibration of of the K-band channels was updated. This caused a slight decrease of the retrieved liquid water path. Updated calibrations have been applied to data from 7/1-9/8. The LWP was decreased slightly as a result of the recalibration. Reprocessed data were archived in November 2010. |

DataStreams: | grwmwrpM1.b1 |
Description: | The temperature and humidity sensor failed causing software crashes and poor retrieval quality. Surface temperature and humidity are incorrect and the bad temperature readings affected the retrievals. Users should completely disregard retrievals from this instrument. |
