The Ozone Report - Measuring Progress through 2003
"The Ozone Report: Measuring Progress through 2003", lays the
groundwork for the planning and analysis needed to track progress toward attaining the nation's
more protective 8-hour ozone standard and reporting the results to the public.
Ozone levels across the nation were down substantially in 2003. The improved air quality resulted from
favorable weather conditions and continuing reductions in emissions of nitrogen oxides (NOx) and
volatile organic compounds (VOCs) - the pollutants that combine in the summer heat to form ozone.
