Subject: AWR/MET/M1 - Missing or suspect PWD data due to heavy snow
Affected 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.

  • pwd_cumul_snow (PWD cumulative snow)
  • pwd_pw_code_1hr (PWD 1 hour present weather code)
  • pwd_mean_vis_1min (PWD 1 minute mean visibility)
  • pwd_cumul_rain (PWD cumulative liquid precipitation)
  • pwd_mean_vis_10min (PWD 10 minute mean visibility)

Affected Datastreams: awrmetM1.b1
Description The PWD was not connected during this period.
Measurements
  • pwd_precip_rate_mean_1min (PWD 1 minute mean precipitation rate)

Subject: AWR/MET/M1 - Probable instrument icing
Affected 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
  • rh_mean (Relative humidity mean)
  • temp_mean (Temperature mean)
  • vapor_pressure_mean (Vapor pressure mean, calculated)

Subject: AWR/MET/M1 - Temperature, RH, Vapor Pressure Incorrect
Affected Datastreams: awrmetM1.b1
Description Temperature and vapor pressure were missing and the RH was flatlined below 0.
Measurements
  • rh_std (Relative humidity standard deviation)
  • vapor_pressure_std (Vapor pressure standard deviation)
  • rh_mean (Relative humidity mean)
  • temp_std (Temperature standard deviation)
  • temp_mean (Temperature mean)
  • vapor_pressure_mean (Vapor pressure mean, calculated)
