Objective This project aims to improve the observation and parametrization of land surface processes with particular emphasis on the hydrological cycle and to improve their treatment in GCM's and catchment models. The work has been divided into the following parts: - Development of an imaging procedure for observing spatial variation in the switch from pre-ponding to ponded conditions and from potential to non-potential evaporation. - Intercomparison of existing land surface modules in single column models. - Formulation of linkage requirements between one-dimensional hydrological models and single column models and harmonisation of input and output routines of hydrologic models and climate models. - Intercomparison and further development of one-dimensional versions of existing hydrologic soil moisture modules. - Objective comparison of GCM routines for handling sub-grid variations in precipitation, potential evaporation and other factors. - Formulation of linkage requirements between spatially variable hydrological models and GCM. Comparison of existing methods and development of improved methods of coping with spatial variability in hydrologic models of soil moisture and surface fluxes. These studies in conjuction with field measurements using remote imaging of switching between atmosphere-controlled and soil-controlled land use surface fluxes, will provide improved software for sensitivity studies as well as recommendations on the optimal design and execution of large scale field experiments (ECHIVAL-EFEDA, HAPEXSAHEL, GEWEX) in order to better understand the importance of the hydrological cycle in global scale.
