Subject: | SGP/EBBR/E18 - Soil Heat Flow #4 Offscale Low; Sensible and Latent Heat Flux Sometimes Incorrect |
DataStreams: | sgp15ebbrE18.b1, sgp30ebbrE18.b1
|
Description: | Soil heat flow #4 was sometimes lower than the lower limit imposed in the EBBR
programming; sensible and latent heat flux were therefore deemed to be suspect during those times.
The cause of the low values is not clear, but the values are not reasonable for the
vegetation type at EF18. |

Subject: | SGP/EBBR/E2 - Net Radiation and Fluxes Incorrect |
DataStreams: | sgp5ebbrE2.b1, sgp15ebbrE2.b1, sgp30ebbrE2.b1
|
Description: | The net radiometer was tipped 37 degrees eastward, resulting in apparent
solar noon being 2.5 hours early. The net radiation error results in incorrect sensible
and latent heat fluxes. |
Measurements: | sgp30ebbrE2.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)

Subject: | SGP/EBBR/E19 - Sensible and latent heat flux and net radiation incorrect |
DataStreams: | sgp5ebbrE19.b1, sgp15ebbrE19.b1, sgp30ebbrE19.b1
|
Description: | Net radiation was too large, resulting in sensible and latent heat fluxes being too large.
The cause of the problem is unknown. |
Measurements: | sgp15ebbrE19.b1:
sgp5ebbrE19.b1: - Radiation, net(net_radiation)
sgp30ebbrE19.b1: - Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux)

Subject: | SGP/EBBR/E2 - AEM Ventilator Dangling - Sensible and Latent Heat Fluxes Incorrect |
DataStreams: | sgp5ebbrE2.b1, sgp15ebbrE2.b1, sgp30ebbrE2.b1
|
Description: | The right AEM ventilator unit with temperature and humidity sensors inside was dangling
from the AEM. Therefore, the gradients of temperature and relative humidity and thus
sensible and latent heat flux are suspect for this period. Often, the fluxes look reasonable. |

DataStreams: | sgp5ebbrE15.b1, sgp15ebbrE15.b1, sgp30ebbrE15.b1
|
Description: | There was water in the bottom dome of the net radiometer.
Net radiation, and sensible and latent heat fluxes were
incorrect during the period. |
Measurements: | sgp5ebbrE15.b1: - Radiation, net(net_radiation)
sgp30ebbrE15.b1: - Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux)

Subject: | SGP/EBBR/E15 - Soil Heat Flow #4 Incorrect |
DataStreams: | sgp15ebbrE15.b1, sgp30ebbrE15.b1
|
Description: | Soil heat flux #4 produced too large a soil heat flow at times, resulting in it exceeding
the qc check limit and causing sensible and latent heat fluxes to be incorrect. |
Measurements: | sgp30ebbrE15.b1: - Average soil heat flow at the surface(surface_soil_heat_flux_avg)
- surface_soil_heat_flux_4
- corr_soil_heat_flow_4
- 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)

Subject: | SGP/EBBR/E18 - SHF #4 Measurements Too Low; Sensible and Latent Heat Fluxes Suspect |
DataStreams: | sgp15ebbrE18.b1, sgp30ebbrE18.b1
|
Description: | Soil heat flow #4 was replaced at the beginning of this period. However, the soil heat
flow measurements from that sensor were sometimes still lower than the lower limit imposed
in the EBBR programming; sensible and latent heat flux were therefore deemed to be
suspect during those times. The cause of the low values could not be determined, but the
values are not reasonable for the vegetation type at EF18.
To remedy the situation, the soil heat flow sensor calibration was changed so that the
sensor provided measurements that resembled the other four soil heat flow sensor
measurements.
Soil heat flow measurements have been reasonable since the calibration change. |
Measurements: | sgp15ebbrE18.b1:
sgp30ebbrE18.b1: - Average soil heat flow at the surface(surface_soil_heat_flux_avg)
- corr_soil_heat_flow_4
