The 1997 Southern California ozone study-NARSTO: Preparation of the 1997 gridded emission inventory
- California Air Resources Board, Sacramento, CA (United States); and others
The 1997 Southern California Ozone Study-North American Research Strategy for Tropospheric Ozone (SCOS97-NARSTO) is intended to provide a milestone in the understanding of relationships between emissions, interbasin transport, and ozone standard exceedances, as well as to facilitate planning for further emission reductions needed to attain the National Ambient Air Quality Standards (NAAQS). Accurate day-specific emission inventories are a crucial element for characterizing air pollution episodes and optimizing the performance of air quality models used to analyze the data collected during SCOS97-NARSTO and develop strategies for attaining the NAAQS. Historically, modeling emission inventories have been criticized for using incomplete day-specific data and for lagging behind the other data (meteorological, air quality) collected in air quality studies. To address these issues, the authors formed an interagency team to develop what they believe is the most comprehensive collection of day-specific emission information for a large study domain (80,000 mi{sup 2}). To make a modeling inventory available in a shorter time frame, they adopted a two-tier approach to the development of the modeling emission inventory which will provide modelers with a fast-track inventory for preliminary modeling to be followed by a more detailed modeling emission inventory which incorporates all of the day-specific information collected during the field study. Data to calculate day-specific emissions were collected for major stationary sources in southern California. The main objective of this study is to develop a spatially and temporally resolved inventory of emission estimates of ROG, NO{sub x}, SO{sub x}, PM, and CO from anthropogenic and certain non-anthropogenic sources. This paper will describe the methods used to create the 1997 gridded emission inventory. The 1997 gridded emission inventory will have a resolution of 2 km.
