A biogenic emission modeling system, BioModel, was developed on the basis of BEIS3 temporal emissions computation algorithms. BioModel uses CORINE land cover database, providing Lithuania land cover data in GeoTIFF geographic data exchange format and MM5 meteorology data in netCDF format and produces spatial-temporal biogenic emissions data, which are rendered immediately (visualized), statistically analyzed and stored in netCDF file. Biogenic emissions were estimated from 11 land use categories. According to BioModel results, highest average isoprene emission rates were produced by conifer forests: in June, 521 g km-2 h-1; in July, 753 g km-2 h-1. Overall average isoprene emission rates from Lithuania (65,281 km2) were 12,714 kg h-1 in June and 18,282 kg h-1 in July (approximately 34% from conifer forests). [ABSTRACT FROM AUTHOR] |
