Das Projekt "Mikrometeorologische Messung des Strahlungs- und Energiehaushaltes an ausgewaehlten Standorten der Nenzlinger Weide und die Integration von Daten von Fernerkundungsplattformen" wird vom Umweltbundesamt gefördert und von Universität Basel, Institut für Meteorologie, Klimatologie und Fernerkundung durchgeführt. The aims of the project: - Fundamental interrelations between boundary layer meteorolgy and biodiversity, - Extraction of ecologically relevant latent infomation from satellite data. The energy balance station (5m pole) at the Nenzlinger Weide was installed and works operationally. A high resoluted precipitation measurement network (24 stations) was built up. In summer 94 energy balance measurements, comparing different methods, were carried out. To have an idea about the spatial and the temporal differentiation of the NDVI, measurements at different meadows in the Swiss Jura were done. The solar radiation and the PAR as well as the radiation budget were calculated for the Nenzlinger Weide and a surrounding of 20km with the help of a radiation model and satellite data (LANDSAT-TM). The special position of the testsite, an optimal offer of shortwave radiation and PAR, could be shown. As well as the variability of the radiation budget, the key function for the heat flux, for several hundred W/m2 for small distances. Within an interdisciplinary biodiversity project the micrometeorological conditions at selected test sites in the Swiss Jura Mountains are studied. Standard micrometeorological measurements are combined with remote sensing techniques from satellite platforms (LANDSAT-TM, NOAA-AVHRR) and surface/airborne thermal camera (AGEMA) to investigate the spatio-temporal modification of the energetic conditions in the area.
