Subject:	SGP/EBBR/E12 - Net radiation too high
DataStreams:	sgp5ebbrE12.b1, sgp15ebbrE12.b1, sgp30ebbrE12.b1
Description:	Net radiation was too high, resulting in overestimated sensible and latent heat fluxes. Net rad domes replaced.
Measurements:	sgp30ebbrE12.b1: Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux) Heat flux, sensible, at 1.5-m height, 30-min intervals(sensible_heat_flux) Radiation, net(net_radiation) sgp15ebbrE12.b1: net_radiation_mv sgp5ebbrE12.b1: Radiation, net(net_radiation)

Subject:	SGP/EBBR/E13 - Net Radiation Too Large
DataStreams:	sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.b1
Description:	The EBBR Net Radiation (Rn) values maintained a ~200 Wm^-2 reading because of poor cable lead connections. Sensible and latent heat fluxes were therefore overestimated. Sensible (H) and latent heat (LE) fluxes can be estimated in the following way: H (new) = H/[1 + (EBBR Rn - SIRS net radiation)/SIRS net radiation] LE (new) = LE/[1 + (EBBR Rn - SIRS net radiation)/SIRS net radiation]
Measurements:	sgp15ebbrE13.b1: net_radiation_mv sgp5ebbrE13.b1: Radiation, net(net_radiation) sgp30ebbrE13.b1: Heat flux, sensible, at 1.5-m height, 30-min intervals(sensible_heat_flux) Radiation, net(net_radiation) Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux)

Subject:	SGP/EBBR/E15 - Sensible and Latent Heat Flux Suspect - Soil Heat Flow 5 Problem
DataStreams:	sgp15ebbrE15.b1, sgp30ebbrE15.b1
Description:	Soil Heat Flow sensor 5 was offscale at times, causing sensible and latent heat fluxes to be incorrect during those times.
Measurements:	sgp30ebbrE15.b1: surface_soil_heat_flux_5 Average soil heat flow at the surface(surface_soil_heat_flux_avg) corr_soil_heat_flow_5 Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux) Heat flux, sensible, at 1.5-m height, 30-min intervals(sensible_heat_flux) soil_heat_flow_5 sgp15ebbrE15.b1: soil_heat_flow_5_mv

Subject:	SGP/EBBR/E7 - Sensible and latent heat fluxes incorrect - soil heat flow 1 problem
DataStreams:	sgp15ebbrE7.b1, sgp30ebbrE7.b1
Description:	Soil Heat Flow 1 was offscale at times, affecting sensible and latent heat fluxes during those times.
Measurements:	sgp15ebbrE7.b1: soil_heat_flow_1_mv sgp30ebbrE7.b1: Average soil heat flow at the surface(surface_soil_heat_flux_avg) corr_soil_heat_flow_1 soil_heat_flow_1 surface_soil_heat_flux_1 Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux) Heat flux, sensible, at 1.5-m height, 30-min intervals(sensible_heat_flux)
