OSTI ID:7203895
Biogenic emissions of volatile organic compounds (VOCs) reportedly play an important role in ozone non-attainment for Atlanta. To better understand this problem, the Southern Oxidant Study participated in an intensive field experiment around Atlanta during the summer of 1992. This paper compares estimates from three different inventories. The first inventory uses the existing Biogenic Emissions Inventory System (BEIS) in the Urban Airshed Model (UAM). UAM-BEIS relies on county-aggregated land use patterns and emission factors dating back to the 1970's. A second inventory incorporates recent (circa 1990) satellite data. Information from the U.S. Forest Service (USFS) is used to increase the coverage of trees in urban areas from 20% to 30%. The third inventory uses USFS forest inventory statistics to compute leaf biomass and tree species composition for about 1 acre forest survey plots, which are extrapolated to about 2000 hectares forest areas as delineated by aerial photography.
