Abstract
The PROMET-family of spatial evapotranspiration models permits modelling of evapotranspiration at field scale, as well as microscale and mesoscale. The model-family consists of a kernel model (a SVAT based on Penman-Monteith and a plant-physiological model for the influence of environmental parameters on canopy resistance) and a spatial modeller, which provides and organises adequate spatial input data on the field, micro and mesoscale. Model results on the field scale show good agreement with measurements. Spatial data is set up using remote sensing and conventional data sources for a 150 X 100 km mesoscale test region in Upper Bavaria and a 7 X 13 km microscale test region embedded in the mesoscale area. The model is run on both scales. Microscale model results are successfully verified using field measurements and water-balance data taken from literature. Mesoscale model results compare well both with microscale model results and satellite-measured patterns of surface temperature.
