Subject: | NSA/METTWR/C1 - Wind Speed data intermittently bad |
DataStreams: | nsamettwrC1.a1, nsamettwrC1.b1 |
Description: | Wind speed at 20m level icing up and wind speed values are intermittently 0 m/s, lower than other sensors and good at times. Heater failure on sensor that prevents icing. |

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. |
