Subject:
SGP/EBBR/E18 - Pressure Low
DataStreams:sgp5ebbrE18.b1, sgp30ebbrE18.b1
Description:
Pressure readings suddenly dropped to unrealistic levels.

Sensible Heat Flux was underestimated and Latent Heat Flux
was overestimated because of this problem.
Suggestions: 
Use the pressure readings from the SMOS at E21 (very near E18) to correct
the sensible and latent heat fluxes, as follows:

Corrected Sensible Heat Flux = SMOS/EBBR pressure * Sensible Heat Flux

Corrected Latent Heat Flux = EBBR/SMOS pressure * Latent Heat Flux

These are approximations with about 1% error.
Measurements:sgp30ebbrE18.b1:
  • Bowen ratio(bowen_ratio)
  • Surface latent heat flux(latent_heat_flux)
  • Surface sensible heat flux(sensible_heat_flux)
  • Atmospheric pressure(atmos_pressure)
