SGP/EBBR/E19 - Wind Direction Data Incorrect (revised)
DataStreams:sgp15ebbrE19.a1, sgp30ebbrE19.a1, sgp5ebbrE19.00, sgp5ebbrE19.a0
Description:
The wind direction sensor was iced stopped by freezing rain, 
resulting in the following values being incorrect:

5 minute:  res_ws, wind_d, sigma_wd
15 minute: mv_wind_d
30 minute: res_ws, wind_d, sigma_wd
Measurements:sgp5ebbrE19.00:
  • null(Raw data stream - documentation not supported)
sgp5ebbrE19.a0:
  • vector wind speed(res_ws)
  • wind direction (relative to true north)(wind_d)
  • standard deviation of wind direction (sigma theta)(sigma_wd)
sgp15ebbrE19.a1:
  • Wind direction (relative to true north)(mv_wind_d)
sgp30ebbrE19.a1:
  • wind direction (relative to true north)(wind_d)
  • standard deviation of wind direction (sigma theta)(sigma_wd)
  • vector wind speed(res_ws)

SGP/EBBR/E19 - Incorrect Tref, Tair Data, Bowen Ratio, latent and sensible heat fluxes
DataStreams:sgp15ebbrE19.a1, sgp30ebbrE19.a1, sgp5ebbrE19.a0
Description:
All Tref and Tair temperatures, plus bowen ratio, latent heat flux,
and sensible heat flux values are incorrect for this period.  This problem
was caused by mistakenly removing the Tref sensor.
Measurements:sgp5ebbrE19.a0:
  • top air temperature(tair_top)
  • Reference Thermistor Temperature(tref)
  • bottom air temperature(tair_bot)
sgp15ebbrE19.a1:
  • Left air temperature(tair_l)
  • Right air temperature(tair_r)
sgp30ebbrE19.a1:
  • latent heat flux(e)
  • top air temperature(tair_top)
  • bottom air temperature(tair_bot)
  • ratio of sensible/latent heat fluxes (Bowen ratio)(bowen)
  • h(h)
  • Reference Thermistor Temperature(tref)
