Subject: | NSA/MWR/C1 - Rain sensor always on |
DataStreams: | nsamwrlosC1.b1, nsamwrtipC1.a1 |
Description: | The rain sensor was always on between 10/5 and 10/23 2006. The user should be aware that not all data flagged as rainy are actually rainy. The problem was caused by a shift in the sensitivity of the rain sensor and was corrected by changing the sensor threshold in the configuration file. |

Subject: | NSA/MWR/C1 - Spikes in air temperature readings |
DataStreams: | nsamwrlosC1.b1, nsamwrtipC1.a1 |
Description: | During this month there are occasional negative spikes in the Tkair variable. The problem may be corrosion in the temperature sensor or the infiltration of water from melting snow. The dewblower was replaced and a new sensor installed |
