SGP/EBBR/E4 - Soil Heat Flux Plate #5
DataStreams:sgp30ebbrE4.b1, sgp15ebbrE4.b1, sgp5ebbrE4.b1
Description:
Soil heat flux plate #5 has indicated high at extremes, for both positive and
negative outputs.  At around -130 watts per meter squared for #5, the other
four heat flux plates indicated approximately half as much.  After
replacement on June 2, 1994 at 1752 GMT, SHF #5 is now very similar to the
other four plates.  The effect on average soil heat flux amounted to only
about 2% of the net radiation value at the worst; this is within the
accuracy of the net radiation measurement and therefore does not require
recalculation of the sensible and latent heat fluxes.
