Seasonal and annual biogenic emission inventories for the U. S. and Canada. Rept. for Jun-Sep 91
The paper summarizes methods and results used to develop an emissions inventory for the U.S. and Canada, used to assess the role of biogenic emissions in ozone formation. Emission inventories were developed at hourly and grid (1/4 x 1/6 degree) levels from input data at the same scales. Resultant emissions were aggregated temporally (to monthly, seasonal, and annual levels) and spatially (to county and state levels). The summary indicates that 53% of annual total biogenic hydrocarbon emissions occur during the summer, but only 4% in the winter. Results are also compared with biogenic emission estimates generated by other researchers, and attempts are made to identify possible causes of observed differences. Recommendations for improvement and further research are discussed. Results of the study will be useful to air quality planners and scientists involved in biological and trace gas research. Historically, ozone control programs based on reductions of known anthropogenic volatile organic compound (VOC) emissions have had limited success in attaining the National Ambient Air Quality Standard. Researchers have therefore been evaluating VOC emission sources not routinely considered in ozone control strategies. One potentially large source of reactive VOCs is emissions from crop and forest foliage.
