Abstract
Abstract The MUREX monitoring the usable soil reservoir experimentally experiment was designed to provide continuous time series of field data over a long period in order to improve and validate the SoilvegetationAtmosphere Transfer SVAT parameterisations employed in meteorological models Intensive measurements were performed for more than three years over fallow farmland in southwestern France To capture the main processes controlling landatmosphere exchanges the local climate was fully characterised and surface water and energy fluxes vegetation biomass soil moisture profiles surface soil moisture and surface and soil temperature were monitored Additional physiological measurements were carried out during selected periods to describe the biological control of the fluxes The MUREX data of 1995 1996 and 1997 are presented Four SVAT models are applied to the annual cycle of 1995 In general they succeed in simulating the main features of the fallow functioning although some shortcomings are revealed
