Abstract
The paper examines the sensitivity of the Regional Oxidant Model (verison 2.2) to changes in emissions. The model is applied to a domain covering most of the eastern United States for the period July 2-8, 1988. Ozone calculations are presented for ten sensitivity tests: (1) base case, (2) 50% decrease in anthropogenic nitrogen oxide (NOx) emissions, (3) 50% decrease in anthropogenic volatile organic compound (VOC) emissions, (4) mobile source VOC emissions increased by a factor of 2.5 and carbon monoxide (CO) emissions increased by a factor of 1.5, (5) run No. 4 with 50% decrease in anthropogenic NOx emissions, (6) run No. 4 with 50% decrease in anthropogenic VOC emissions, (7) zero mobile source emissions, (8) soil NO emissions increased to reflect higher levels of fertilizer application, (9) biogenic VOC emissions for corn reduced to reflect a more recent (and substantially lower) emission factor, and (10) all anthropogenic emissions set to zero.
