Subject: | GAN/MET/M1 - Intermittent PWD alarm |
DataStreams: | ganmetM1.b1 |
Description: | Intermittent backscatter alarms were tripping on the PWD suggesting something was blocking (dew) or getting into the measurement path (spider or ants). Problem resolved 10/9 with no clear indication of the cause. |

Subject: | GAN/RAIN/M1 - Incorrect precipitation data |
DataStreams: | ganrainM1.b1 |
Description: | The weighing bucket rain gauge was not reporting rainfall when other sensors were reporting rainfall, possibly due to configuration or connection problems. |

Subject: | GAN/MWR3C/M1 - Radiometer instability |
DataStreams: | ganmwr3cM1.b1 |
Description: | The radiometer showed intermittent instability in the 30 GHz and 89 GHz channel. There was a calibration shift between Jan 4 and Jan 8 and a calibration instability between Jan 12 and Jan 20. It may be possible to recalibrate the data when a recalibration algorithm is developed. |

Subject: | GAN/RAIN/M1 - Noise in sensor 3 |
DataStreams: | ganrainM1.b1 |
Description: | Sensor 3 was noisy after data collection resumed. This noise cleared up on its own by 20111212 123000 and the noise will only effect the raw data. The ingest which produces the b1 version of the data removes the noise. |
