Abstract

The diurnal and seasonal emission course from plants is controlled by light and temperature. Therefore, predicting the light and temporal distribution within a forest canopy is an important requirement for emission estimates. A complex GIS-based solar radiation model was developed for scaling of biogenic emissions from complex terrain and from forest canopies. A digital elevation model represented the canopy surface of the St Quercio pine/oak forest in Italy. Temperature values were linked to the radiation output and emissions were parameterized for light and temperature acc. To Tingeys and Guenthers emission algorithms. Model runs were performed for 26 May 1994 to 3rd August 1994, calculated fluxes were validated with datasets of BEMA-campaigns.
