Subject:
AWR/MET/M1  - Missing or suspect PWD data due to heavy snow
DataStreams:awrmetM1.b1
Description:
Heavy snow interfered with the instrument lenses causing backscatter and missing data. 
Data from the present weather detector during this time is suspect or missing.
Measurements:awrmetM1.b1:
  • pwd_cumul_rain
  • PWD 1 minute mean precipitation rate(pwd_precip_rate_mean_1min)
  • pwd_pw_code_15min
  • PWD 1 minute mean visibility(pwd_mean_vis_1min)
  • PWD 10 minute mean visibility(pwd_mean_vis_10min)

Subject:
AWR/MET/M1 - Probable instrument icing
DataStreams:awrmetM1.b1
Description:
The temperature and relative humidity sensor behaved suspiciously during this time. 
Temperature and relative humidity readings did not trend inversely, as expected. Ice buildup on 
the instrument is the probable cause.
Measurements:awrmetM1.b1:
  • Temperature mean(temp_mean)
  • Humidity, relative, at 2-m height, 1-min avg(rh_mean)
  • Vapor pressure mean, calculated(vapor_pressure_mean)
