Subject:
NSA/MWR/C1 - TKAIR sensor failure
DataStreams:nsamwrlosC1.b1
Description:
Between 7/14 and 7/28 the tkair variable is missing most of the time and sometimes has 
large negative spikes.  On 7/28, the sensor was cleaned of corrosion and the readings came 
back to normal.
Measurements:nsamwrlosC1.b1:
  • Ambient temperature(tkair)

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.
Measurements:nsamwrtipC1.a1:
  • Water on Teflon window (1=WET, 0=DRY)(wet_window)

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
