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/TSI/M1 - Mirror reflection |
DataStreams: | grwtsiskycoverM1.b1 |
Description: | A deformity in the mirror produced an anomolous refraction within the mirror surface that appeared in the images as a white streak near the top of the mirror and shadowband. The mirror was replaced on 6/19. |

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. |

Subject: | GRW/TSI/M1 - Shadowband Misalignment |
DataStreams: | grwtsiskycoverM1.b1, grwtsiskyimageM1.a1, grwtsicldmaskM1.a1 |
Description: | The shadowband was intermittently misaligned and not completely masking the sun because the mirror became loose from the shaft while being polished. The shadowband was realigned on 1/14 but by 1/27 was again slightly misaligned. The instrument was reoriented with true north on 1/27 and the shadowband adjusted again on 1/31. The problem was corrected on 2/2 when the mirror mounting was tightened and the shadowband realigned. |

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. |

Subject: | GRW/MWRP/M1 - Reprocessed: Updated calibration coefficients |
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. |

Subject: | GRW/MWRP/M1 - Temp/RH sensor failure |
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. |

Subject: | GRW/TSI/M1 - Shadowband Misalignment |
DataStreams: | grwtsiskycoverM1.b1 |
Description: | The shadowband was slightly out of alignment because one corner of the instrument stand had sunk about 25mm. The stand was releveled and the TSI re-aligned. |
