Subject: | NSA/METTWR/C1 - All 10m level Data Missing |
DataStreams: | nsamettwr4hC1.b1 |
Description: | After prolonged power outage and many power spikes during the outage all data from the 10m level are missing. Blown fuse on the power supply was replaced once the temperatures warmed enough to allow the lowering of the tower carriages. |

Subject: | NSA/METTWR/C1 - Incorrect Maximum for Precip Values |
DataStreams: | nsamettwr4hC1.b1 |
Description: | The max values for cumulative rain sum of 99 mm and the rain rate of 999 mm/hr are incorrect. In communication with the manufacturer it has been found that the manual was in error. The actual max values of the cumulative rain sum is 99.99 mm and the rain rate is 999.99 mm/hr. |

Subject: | NSA/METTWR/C1 - CMH mirror dirty |
DataStreams: | nsamettwr4hC1.b1 |
Description: | The CMH mirror was in need of cleaning. The data is suspect from 05/28/05 through 07/04/05 as intermittently poor readings occurred. After 07/04/05 the data was incorrect as the mirror was excessively dirty. |

Subject: | NSA/METTWR/C1 - Tower Maintenance |
DataStreams: | nsamettwr4hC1.b1 |
Description: | The booms of the tower were lowered for sensor replacement, calibration, and tower maintenance. During the maintenance and sensor replacement data are frequently missing. Where data are available, they are not or may not be representative because the booms were at the base of the tower during the time period listed. The chilled mirror measurements were not affected by the maintenance. |
