Subject: | NSA/MET/C1 - Temp/RH/wind data questionable |
DataStreams: | nsametC1.b1, nsatwrC1.b1 |
Description: | New wind sensors and new T/RH probes were being installed during this time period. The tower booms were lowered and much of the data collected were not at listed heights nor were the data accurate due to configurations during install. |

Subject: | NSA/MET/C1 - CMH offline |
DataStreams: | nsametC1.b1 |
Description: | Beginning 1/24/2011, the CMH went offline resulting in missing temperature and dewpoint measurements and erroneous vapor pressure, saturation vapor pressure, and RH measurements. Problem fixed with a power cycle. |

DataStreams: | nsametC1.b1, nsatwrC1.b1 |
Description: | 2m, 10m, 20m wind sensors went off-line 5/17 due to GFCI tripping caused by failing CMH. The 2m and 20m data wind sensor returned 6/6, but the 10m remained offline until 7/20 as the sensor was damaged. |

Subject: | NSA/MET/C1 - CMH communication failure |
DataStreams: | nsametC1.b1 |
Description: | CMH lost communication with datalogger. All values from CMH were -6999 during this time resulting in the CMHRH flatlining at 100%. Communications was intermittent during entire time period. |

Subject: | NSA/MET/C1 - CMH failure |
DataStreams: | nsametC1.b1 |
Description: | Starting 14:17 GMT on 12/4/2011 the CMH Dew Point began reporting missing value, CMH relative humidity was flat-lining at 100% and CMH saturated vapor pressure was flat-lined at a high value. This condition continued very intermittently for several months. Issue was frosting and a failed ventilation fan. |
