“…Geographical scales thereby ranged from particular sites up to regional catchments (100 000 km 2 ). Thereby, the derivatives of the model, implemented in various programming languages, have been integrated in -the SVAT scheme PROMET (P rocesses of Radiation, Mass and Energy T ransfer) for distributed, physically based water balance simulations including sophisticated formulations of the matter and energy fluxes in the soil, plants and in the atmospheric boundary layer (Mauser and Bach, 2009;Strasser and Mauser, 2001;Mauser and Schädlich, 1998;Strasser, 1998;Taschner et al, 1998),…”
