SGP/EBBR/E26 - Sensible and Latent Heat Fluxes Affected by bad temp sensor
DataStreams:sgp15ebbrE26.b1, sgp30ebbrE26.b1, sgp5ebbrE26.b1
Description:
The left Thum (temperature of the humidity sensor chamber) measurement was incorrect at 
times, affecting several measurements, including the sensible and latent heat fluxes.
Measurements:sgp15ebbrE26.b1:
  • Temperature of left humidity sensor chamber(rr_thum_l)
sgp5ebbrE26.b1:
  • Temperature of the top humidity chamber(thum_top)
  • bottom vapor pressure(vp_bot)
  • Temperature of bottom humidity sensor chamber(thum_bot)
  • top vapor pressure(vp_top)
sgp30ebbrE26.b1:
  • ratio of sensible/latent heat fluxes (Bowen ratio)(bowen)
  • latent heat flux(e)
  • Temperature of the top humidity chamber(thum_top)
  • bottom vapor pressure(vp_bot)
  • top vapor pressure(vp_top)
  • Temperature of bottom humidity sensor chamber(thum_bot)
  • h(h)

SGP/EBBR/E20 - Reprocess: Wind Direction 65 Degrees Low
DataStreams:sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:
The wind direction sensor reported wind directions that were 65 degrees too low because of 
a mis-alignment.

This bias should have no effect on the res_ws or sigma_wd measurements.

The wind direction data could be re-processed by adding 65 degrees.
Measurements:sgp30ebbrE20.b1:
  • wind direction (relative to true north)(wind_d)
sgp15ebbrE20.b1:
  • Wind direction (relative to true north)(mv_wind_d)
sgp5ebbrE20.b1:
  • wind direction (relative to true north)(wind_d)

SGP/EBBR/E9 - Net Radiation Incorrect
DataStreams:sgp15ebbrE9.b1, sgp30ebbrE9.b1, sgp5ebbrE9.b1
Description:
There was water in the net radiometer.  

The net radiation data was incorrect.
Measurements:sgp15ebbrE9.b1:
  • Net radiation(mv_q)
sgp5ebbrE9.b1:
  • net radiation(q)
sgp30ebbrE9.b1:
  • latent heat flux(e)
  • h(h)
  • net radiation(q)
