Abstract |
Measurements of 0600 to 0900 AM speciated NMOC compounds obtained from 19 urban areas located throughout the United States during a 1985 sampling program are presented. The cities sampled all experienced ozone levels above the National Ambient Air Quality Standard (NAAQS) of 0.12 ppm. Speciated NMOC information is useful for both the development of photochemical ozone models and the evaluation of the sources contributing to ambient air concentration levels. Using a simple box model it appears that NMOC composition has the greatest impact on ozone formation at the lower NMOC to NOx ratios. |
