SGP/EBBR/E25 - Wind Direction and Speed Data Incorrect
DataStreams:sgp5ebbrE25.00, sgp30ebbrE25.b1, sgp15ebbrE25.b1, sgp5ebbrE25.b1
Description:
The wind direction and speed sensors were iced stopped by freezing rain, 
resulting in the following values being incorrect:

5 minute:  wind_s, res_ws, wind_d, sigma_wd
15 minute: wind_s, mv_wind_d
30 minute: wind_s, res_ws, wind_d, sigma_wd
Suggestions: 
Measurements:sgp5ebbrE25.b1:
  • Wind direction vector mean standard deviation(wdir_vec_std)
  • Wind speed vector mean(wspd_vec_mean)
  • Wind speed arithmetic mean(wspd_arith_mean)
  • Wind direction vector mean(wdir_vec_mean)
more
sgp15ebbrE25.b1:
  • Wind direction vector mean (mV)(wdir_vec_mean_mv)
  • Wind speed arithmetic mean(wspd_arith_mean)
more
sgp5ebbrE25.00:
  • (Raw data stream - documentation not supported)
