NSA/MET/C1 - CMH and 10m winds failure
DataStreams:nsametC1.b1
Description:
At 0513GMT on 1/23 the atmos_pressure and CMH - temp, RH, DP & Sat. VP changed abruptly to 
unlikely values. The 10m winds failed at 1420GMT.

The CMH was repaired on 02/04/2010 at 2254GMT and the 10m winds sensor was replaced on 
02/05/2010 at 2100GMT.

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.

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.
Measurements:nsametC1.b1:
  • Wind speed, lower, 1-min avg(wspd_arith_mean)

resulting in the CMHRH flatlining at 100%. Communications was intermittent during entire 
time period.
