BENJEY, W. G. AND E. COOTER. INTER-ANNUAL AND SEASONAL VARIABILITY OF METEOROLOGICALLY-INFLUENCED EMISSIONS. Presented at 14th Annual International Emission Inventory Conference, Las Vegas, NV, April 11 - 14, 2005.
Impact/Purpose:
The objective of this work is to investigate the impact of global climate change on the regional air quality of the United States. Impacts of climate change on meteorological patterns and primary source emissions are investigated as primary elements influencing future air quality.
Description:
The U.S. Environmental Protection Agency (EPA) is a participant in the U.S. Global Change Research Program (CGRP). The air quality portion of the GCRP addresses the effect on air quality attributable to climate change in the intermediate future (e.g., 2050). The first phase of the program examines the change in air quality with respect to climate change from 2000 to 2050, using a static emission inventory for 2001, except for biogenic and mobile source emissions which are modeled to vary with meteorology. Between five and ten years of modeled meteorology data will be used to define the climate of 2000 and 2050, respectively. This presentation is a preliminary examination of the inter-annual and inter-seasonal variability of meteorologically-influenced emissions over a five-year base study period centered on 2000.
