Estimation Of Surface Fluxes Over Canopies During MAC-europe 1991 Campaign Using Combined Microwave And Optical Data

Abstract

An intensive field campaign in the Orgeval watershed, France, part of the NASA MAC-Europe'91 experiment, is described. A two-layer surface energy balance model, based on Deardorff' s formalism, has been tested and validated, in order to incorporate combined optical (visible to thermal infrared) and active microwave data. Retrieving evaporation fluxes using this synergy seems to be a reliable technique. Further work should increase temporal and spatial variability of remote sensed parameters to get better physical relationships between them and surface fluxes.
