P095: Ozone Modeling System and Emission Control Strategies for the Lake Tahoe Basin

There is growing concern about the effects of ozone (O3) on air quality in the Lake Tahoe Basin. Ozone levels in the Tahoe Basin have been increasing and have led to exceedances of current California air quality standards. This trend can have serious implications with respect to human and ecosystem health. This area is currently designated as a nonattainment-transitional zone for O3 by the California Air Resources Board. In response to the need for a robust emission control strategy, a comprehensive meteorological and air quality modeling study has been completed to investigate the characteristics and causes of the episodes of elevated ozone.
