SGP/EBBR/E8 - Fluxes Incorrect; Left Humidity Near Zero
DataStreams:sgp15ebbrE8.b1, sgp30ebbrE8.b1, sgp5ebbrE8.b1
Description:
The left humidity was intermittently incorrect, therefore the sensible and latent heat 
fluxes were also.
Measurements:sgp30ebbrE8.b1:
  • top vapor pressure(vp_top)
  • ratio of sensible/latent heat fluxes (Bowen ratio)(bowen)
  • latent heat flux(e)
  • Top humidity(hum_top)
  • h(h)
  • Bottom humidity(hum_bot)
  • bottom vapor pressure(vp_bot)
sgp5ebbrE8.b1:
  • Bottom humidity(hum_bot)
  • bottom vapor pressure(vp_bot)
  • Top humidity(hum_top)
  • top vapor pressure(vp_top)
sgp15ebbrE8.b1:
  • Left relative humidity(mv_hum_l)

SGP/EBBR/E8 - Sensible and Latent Heat Flux Suspect
DataStreams:sgp15ebbrE8.b1, sgp30ebbrE8.b1, sgp5ebbrE8.b1
Description:
The left humidity sensor produced large spikes frequently.  This resulted in incorrect 
measurements of vapor pressure gradient and thus calculations of sensible and latent heat 
flux.
Measurements:sgp30ebbrE8.b1:
  • top vapor pressure(vp_top)
  • ratio of sensible/latent heat fluxes (Bowen ratio)(bowen)
  • latent heat flux(e)
  • Top humidity(hum_top)
  • h(h)
  • Bottom humidity(hum_bot)
  • bottom vapor pressure(vp_bot)

  • bottom vapor pressure(vp_bot)

SGP/EBBR/E9 - Wind Speed Incorrect
DataStreams:sgp15ebbrE9.b1, sgp30ebbrE9.b1, sgp5ebbrE9.b1

Measurements:sgp15ebbrE9.b1:
  • scalar wind speed(wind_s)
sgp5ebbrE9.b1:
  • scalar wind speed(wind_s)
  • vector wind speed(res_ws)

SGP/EBBR/E8 - Sensible and Latent Heat Fluxes and Net Radiation Incorrect
DataStreams:sgp15ebbrE8.b1, sgp30ebbrE8.b1, sgp5ebbrE8.b1
Description:
The net radiometer top dome was broken and water had gotten into it.

Sensible and latent heat fluxes and net radiation were therefore incorrect.
Measurements:sgp30ebbrE8.b1:
  • latent heat flux(e)
  • net radiation(q)
  • h(h)
sgp5ebbrE8.b1:
  • net radiation(q)

SGP/EBBR/E8 - Failed Temp/RH sensor
DataStreams:sgp15ebbrE8.b1, sgp30ebbrE8.b1, sgp5ebbrE8.b1
Description:
The right Temperature-Humidity sensor failed. The measured temperature gradients were 
incorrect and thus the sensible and latent heat fluxes were incorrect for this extended 
period.

The sensor was replaced March 6.
Measurements:sgp30ebbrE8.b1:
  • top vapor pressure(vp_top)
  • ratio of sensible/latent heat fluxes (Bowen ratio)(bowen)
  • latent heat flux(e)
  • Temperature of the top humidity chamber(thum_top)
  • h(h)
  • bottom vapor pressure(vp_bot)
  • Temperature of bottom humidity sensor chamber(thum_bot)
sgp5ebbrE8.b1:
  • Temperature of the top humidity chamber(thum_top)
  • Temperature of bottom humidity sensor chamber(thum_bot)

Description:
The wind direction was misaligned by 180 degrees. If the wind direction was 180 degrees or 
less, add 180 degrees to give the correct direction.  If the wind direction was greater 
than 180 degrees, subtract 180 degrees to give the correct direction.
Measurements:sgp5ebbrE4.b1:
  • wind direction (relative to true north)(wind_d)
