Modelling the energy exchange between the atmosphere and forests

The ACASA model of the University of California, Davis, was successfully adapted for two intensive observation periods in the Fichtelgebirge of the EGER project of the Department of Micrometeorology, University of Bayreuth. A comprehensive sensitivity analysis of the model for the site was carried out in cooperation with the partners from California, and thereby a better adjustment of the model was achieved for the site. The vast experimental data collected within the EGER project allowed the investigation of the exchange of energy and matter not only for the stand as a whole but also for very differentiated processes within the soil-vegetation-atmosphere system, and to validate modeling with ACASA. That way the representation of some processes within the model was checked and in a few cases improved. The cooperation with the partners from California was stimulated by visits of Prof. Kyaw Tha Paw U at the University of Bayreuth and of Katharina Staudt in California in the context of international conferences with ACASA working group meetings.
