Subject:
GRW/MET/M1 - Tower lowered during installation
DataStreams:grwmetM1.b1
Description:
Data was collected during set up and installation.  Any data collected is suspect due to 
the tower being lowered and calibration checks occurring.  The data should be viewed 
critically before being used.
Measurements:grwmetM1.b1:
  • Wind direction vector mean(wdir_vec_mean)
  • pwd_err_code
  • Vapor pressure mean, calculated(vapor_pressure_mean)
  • rh_std
  • Wind speed, lower, 1-min avg(wspd_arith_mean)
  • pwd_pw_code_inst
  • Atmospheric pressure(atmos_pressure)
  • temp_std
  • wdir_vec_std
  • Humidity, relative, at 2-m height, 1-min avg(rh_mean)
  • Temperature mean(temp_mean)
  • PWD 10 minute mean visibility(pwd_mean_vis_10min)
  • vapor_pressure_std
  • ORG precipitation rate mean(org_precip_rate_mean)
  • PWD 1 minute mean precipitation rate(pwd_precip_rate_mean_1min)
  • Wind speed vector mean(wspd_vec_mean)
  • pwd_cumul_rain
  • PWD 1 minute mean visibility(pwd_mean_vis_1min)
  • pwd_pw_code_15min
  • pwd_pw_code_1hr

Subject:
GRW/MET/M1 - Temperature/RH aspirator failure
DataStreams:grwmetM1.b1
Description:
The aspirator fan on the solar shield failed causing incorrect readings on the temp, RH 
and calculated variables.
Measurements:grwmetM1.b1:
  • Temperature mean(temp_mean)
  • vapor_pressure_std
  • Vapor pressure mean, calculated(vapor_pressure_mean)
  • rh_std
  • temp_std
  • Humidity, relative, at 2-m height, 1-min avg(rh_mean)

Subject:
GRW/MET/M1 - Precipitation data bias
DataStreams:grwmetM1.b1
Description:
Mounting of the optical rain gauge and present weather sensor on cross-arms affixed to the 
meteorological tower introduced a precipitation rate bias. Precipitation data at this 
site should be used with caution.
Measurements:grwmetM1.b1:
  • ORG precipitation rate mean(org_precip_rate_mean)
  • PWD 1 minute mean precipitation rate(pwd_precip_rate_mean_1min)
  • pwd_cumul_rain
