Measurements of the radiation balance and surface energy fluxes collected during HAPEX-MOBILHY are presented for Les Landes pine forest in southwest France. The energy flux measurements, made by the eddy correlation method, are analysed in the framework of the Penman Monteith equation to provide estimates of the aerodynamic and surface conductances. Evaporation data are fitted to a model which describes the variation of the surface conductance as a nonlinear function of solar radiation, specific humidity deficit and temperature. These results are compared with a previous application of the same model to the data from Thetford Forest in the U.K. There was insufficient variation in soil moisture deficit during the HAPEX-MOBILHY Special Observing Period to allow the dependence of surface conductance on soil moisture to be modelled.
