Abstract
|
|
|
The estimation of a biogenic volatile organic compound (BVOC, especially isoprene) and the influence of isoprene
emissions on ozone concentrations in the Greater Busan Area (GBA) were carried out based on a numerical modeling
approach during a high ozone episode. The BVOC emissions were estimated using a biogenic emission information system (BEIS v3.14) with vegetation data provided by the forest geographical information system (FGIS), land use data provided by the environmental geographical information system (EGIS), and meteorological data simulated by the MM5. Ozone simulation was performed by two sets of simulation scenarios: (1) without (CASE1) and (2) with isoprene emissions (CASE2). The isoprene emission (82 ton day-1) in the GBA was estimated to be the most dominant BVOC followed by methanol (56) and carbon monoxide (28). Largest impacts of isoprene emissions on the ozone concentrations
(CASE2-CASE1) were predicted to be about 4 ppb in inland locations where a high isoprene was emitted and to be about 2
ppb in the downwind and/or convergence regions of wind due to both the photochemical reaction of ozone precursors (e.g.,high isoprene emissions) and meteorological conditions (e.g., local transport).
