“Exchanges of Aggregate Air Nitrogen Emissions and Watershed Nitrogen Loads”
Dennis, R., S. Napelenok, L. Linker, AND M. Rutkowski. “Exchanges of Aggregate Air Nitrogen Emissions and Watershed Nitrogen Loads”. Presented at CERF 22nd Biennial Conference, San Diego, CA, November 05 - 08, 2013.
An approach has been developed to define transfer coefficients that can be used to convert changes in air emissions to changes in air deposition and subsequently to changes in loads delivered to the Bay. This approach uses a special CMAQ version that quantitatively attributes watershed and Bay deposition to individual Bay state emissions. The approach is described in the presentation.
The National Exposure Research Laboratory (NERL) Atmospheric Modeling and Analysis Division (AMAD) conducts research in support of EPA mission to protect human health and the environment. AMAD research program is engaged in developing and evaluating predictive atmospheric models on all spatial and temporal scales for forecasting the air quality and for assessing changes in air quality and air pollutant exposures, as affected by changes in ecosystem management and regulatory decisions. AMAD is responsible for providing a sound scientific and technical basis for regulatory policies based on air quality models to improve ambient air quality. The models developed by AMAD are being used by EPA, NOAA, and the air pollution community in understanding and forecasting not only the magnitude of the air pollution problem, but also in developing emission control policies and regulations for air quality improvements
