Subject: | NSA/METTWR/C1 - All data from 10m Level Missing |
DataStreams: | nsamettwr4hC1.b1 |
Description: | The winch that lowers the tower booms failed. Manual testing of the motor and winch allowed the booms to be lowered briefly and then raised back into position. A heavy freezing rain/icing event added extra weight to the booms. This extra weight was suspected as the cause as to why the 10m boom became disconnected. After a new motor was installed and all booms were lowered and re-raised the 10m level came back on line. |

Subject: | NSA/METTWR/C1 - Missing CMH data |
DataStreams: | nsamettwr4hC1.b1 |
Description: | CMH data are missing. Corrosion in the serial data line connections caused a loss of communication with the CMH. |

Subject: | NSA/METTWR/C1 - 2m T/RH probe aspirator fan failed |
DataStreams: | nsamettwr4hC1.b1 |
Description: | The aspirator fan for the 2m level T/RH probe failed. This caused higher than normal readings for temp and RH and artificially smoothed the data. |

Subject: | NSA/METTWR/C1 - Wind direction sensor frozen |
DataStreams: | nsamettwr4hC1.b1 |
Description: | After a power outage the 40m wind direction sensor was frozen. Data from this sensor was not representative of the true winds. |

Subject: | NSA/METTWR/C1 - 40m Wind Direction Data Suspect |
DataStreams: | nsamettwr4hC1.b1 |
Description: | The 40m wind direction data was suspect due to icing on the vane or a failing shafter heater or a combination of both. The affected data can be easily seen on comparison plots with other levels data or by checking the standard deviation of the 40m wind direction. Any standard deviation of less than 0.10 degrees for the 40m level suggest a sluggish/ice affected sensor. |
