SPATIAL VARIATIONS IN BIOGENIC EMISSIONS FOR LITHUANIA
Description (Dublin Core)
eng
The numerical modelling of biogenic volatile organic compounds (BVOCs) monoterpene and isoprene was carried out
using three-dimensional (3D) mesoscale meteorological and photochemical atmospheric models. Emission factors, combined with
land cover data represented by the appropriate 11 Biogenic Emission Inventory System (BEIS) vegetation categories, along with
environmental correction factors were used to derive emission fluxes of isoprene, monoterpene and other VOCs for Lithuania. Moreover, simulated data have been combined with BEIS data using a Geographic Information System (GIS) to appropriately
represent the spatial distribution of BVOCs. Calculations showed that the coniferous trees are the main sources of biogenic emissions. The highest emission fluxes of biogenic VOC are estimated to be in the region of the south-south eastern Lithuania, which has the largest forest coverage in Lithuania and the major part of these forests consist of coniferous forests. The total simulated isoprene emission flux from Lithuania (65281 km2) reached 12710 kg h-1 in June and 18280 kg h-1 in July (approximately 34 % from coniferous forests). On the other hand, monoterpene average emission flux from Lithuania was found to be 4080 kg h-1 in June and 5330 kg h-1 in July (approximately 50% from coniferous forests).
