SGP/EBBR/E22 - Net Radiation and Sensible and Latent Heat Fluxes Incorrect
DataStreams:sgp15ebbrE22.b1, sgp30ebbrE22.b1, sgp5ebbrE22.b1
Description:
Rain entered the net radiometer, causing net radiation, and thus sensible and latent heat 
fluxes, to be too large.
Measurements:sgp5ebbrE22.b1:
  • net radiation(q)
sgp30ebbrE22.b1:
  • h(h)
  • net radiation(q)
  • latent heat flux(e)
sgp15ebbrE22.b1:
  • Net radiation(mv_q)

SGP/EBBR/E22 - Wind Direction Incorrect
DataStreams:sgp15ebbrE22.b1, sgp30ebbrE22.b1, sgp5ebbrE22.b1
Description:
Wind direction was flat-lining at 135 degrees and occasionally changed to 0.4 degrees.
Measurements:sgp30ebbrE22.b1:
  • wind direction (relative to true north)(wind_d)
  • standard deviation of wind direction (sigma theta)(sigma_wd)
  • vector wind speed(res_ws)
sgp5ebbrE22.b1:
  • vector wind speed(res_ws)
  • wind direction (relative to true north)(wind_d)
  • standard deviation of wind direction (sigma theta)(sigma_wd)
sgp15ebbrE22.b1:
  • Wind direction (relative to true north)(mv_wind_d)

SGP/EBBR/E20 - Reprocess: Wind Direction 20 Degrees Low
DataStreams:sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:
The EBBR wind direction was found to be misaligned 20 degrees low. 

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