P063: Distribution of Ozone, Ozone Precursors and Gaseous Components of Atmospheric Nitrogen Deposition in the Lake Tahoe Basin

This study characterized spatial and temporal distribution of ozone (O3), O3 precursors, O3 formation, and gaseous pollutants that are important contributors to atmospheric nitrogen (N) deposition in the Lake Tahoe Basin. Passive samplers were used to monitor O3, nitric oxide (NO), nitrogen dioxide (NO2), ammonia (NH3), nitric acid (HNO3) and volatile organic compounds (VOCs) on a network of 34 sites inside and outside of the basin. Using statistical and geostatistical models, distribution maps of the measured compounds were created for the entire basin.
