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.

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.

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

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:sgp30ebbrE18.b1:
  • 5 cm soil heat flow corrected for soil moisture content, site 4(c_shf4)
  • 5 cm soil heat flow, site 4(shf4)
