NSA/METTWR/C1 - Wind Speed data intermittently bad
DataStreams:nsamettwrC1.a1, nsamettwrC1.b1
Description:
Wind speed at 20m level icing up and wind speed values are intermittently
0 m/s, lower than other sensors and good at times.  Heater failure on sensor
that prevents icing.
Measurements:nsamettwrC1.a1:
  • Minimum Wind Speed(wind_spd_min)
  • wind_spd_sd
  • Mean Wind Speed(wind_spd_mean)
  • Vector-averaged Wind Speed(wind_spd_vec_avg)
  • Maximum Wind Speed(wind_spd_max)
nsamettwrC1.b1:
  • Maximum Wind Speed(wind_spd_max)
  • wind_spd_out_of_range_error
  • Mean Wind Speed(wind_spd_mean)
  • wind_spd_sd
  • Minimum Wind Speed(wind_spd_min)
  • Vector-averaged Wind Speed(wind_spd_vec_avg)

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.
Measurements:nsametC1.b1:
  • cmh_dew_point
  • cmh_temp
  • cmh_vapor_pressure
  • cmh_sat_vapor_pressure
  • cmh_rh

NSA/MET/C1 - CMH Failure
DataStreams:nsametC1.b1
Description:
The Chilled Mirror Hydrometer (CMH) developed a short in the wiring harness. All CMH data 
missing or incorrect during the period listed.
Measurements:nsametC1.b1:
  • cmh_dew_point
  • qc_cmh_dew_point
  • qc_cmh_rh
  • cmh_temp
  • cmh_vapor_pressure
  • qc_cmh_vapor_pressure

Subject:
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 arithmetic mean(wspd_arith_mean)
  • Wind speed vector mean(wspd_vec_mean)
  • wdir_vec_std
  • Wind direction vector mean(wdir_vec_mean)
nsatwrC1.b1:
  • wdir_vec_std
  • Wind speed arithmetic mean(wspd_arith_mean)
  • Wind direction vector mean(wdir_vec_mean)
  • Wind speed vector mean(wspd_vec_mean)
