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. |

Subject: | NSA/MET/C1 - Wind sensor data missing |
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 - Frosting/Condensation |
DataStreams: | nsametC1.b1 |
Description: | Beginning 20111108, the PWD began occasionally frosting over, signaling an alarm code and sometimes causing the PWD to stop reporting. A new PWD with hood heater attachment was installed 20130222. |

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. |
