SGP/EBBR/E4 - Instrument problem
DataStreams:sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:
Wind direction was flat lining near zero and incorrect.
Measurements:sgp5ebbrE4.b1:
  • wind direction (relative to true north)(wind_d)
  • standard deviation of wind direction (sigma theta)(sigma_wd)
sgp30ebbrE4.b1:
  • wind direction (relative to true north)(wind_d)
  • standard deviation of wind direction (sigma theta)(sigma_wd)
sgp15ebbrE4.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/E22 - H and LE Incorrect
DataStreams:sgp15ebbrE22.b1, sgp30ebbrE22.b1
Description:
Soil Heat Flow 1 bounced around and went offscale at times, resulting in the EBBR program 
setting sensible and latent heat fluxes to 9999es.

The problem ended during a PM visit, possibly because of routine checks and tightening of 
leads in terminal strips.
Measurements:sgp30ebbrE22.b1:
  • soil heat flow, site 1(g1)
  • 5 cm soil heat flow, site 1(shf1)
  • h(h)
  • 5 cm soil heat flow corrected for soil moisture content, site 1(c_shf1)
  • average surface soil heat flow(ave_shf)
  • latent heat flux(e)
sgp15ebbrE22.b1:
  • Soil heat flow 1(mv_hft1)
