Description: Das Projekt "Waerme, Feuchtigkeit und Massenaustauschprozesse in regionalem Massstab in nicht-homogenem Gelaende" wird vom Umweltbundesamt gefördert und von Universität Karlsruhe, Institut für Meteorologie und Klimaforschung durchgeführt. Observational, theoretical and modelling tools will be used to obtain areal averages of surface fluxes of momentum, heat and water vapour as well as the mean values of wind velocity, temperature and humidity at levels relevant for GCM's and climate models. The work will be concentrated on a specific area, where data from a dense observational network is available, and which is topographically of moderate complexity. The area is the Upper Rhine Valley between Karlsruhe and Basel. Satellite imagery will be used for the elaboration of land use maps and for the monitoring of surface temperature in space and time. Meteosat data will be used to provide high temporal resolution of the temperature, and will be calibrated with AVHRR data to achieve a higher spatial resolution. Landsat TM data will be used together with digital elevation data for the elaboration of the land use data. Surface observations will be analysed in terms of the components of the surface energy fluxes and the mean quantities. Vertical profiles of pertinent meteorological parameters will be measured. The surface measurements will cover areas typical of climate model grid boxes and will be done over a number of typical sites. The data will be analysed using microscale and mesoscale modelling. A diagnostic microscale model will be operated for integration of the information on the scale of the heterogeneities into suitable averages for mesoscale dynamical modelling (1 km scale). A nonhydrostatic mesoscale model (KAMM) will be used to aggregate the microscale exchange processes up to 100 km scales. The end result will be the development of methods to compile observational information into boundary conditions suitable for GCM's and climate models, of methods to deal with subgrid scale inhomogeneities, and of improved surface flux parametrization schemes for use in such models.
