Impact/Purpose:
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.
Description:
We present highlights of the results obtained in the second phase of the Air Quality Model Evaluation International Initiative (AQMEII) that was completed in May 2014. Activities in this phase were focused on the application and evaluation of coupled meteorology-chemistry models over both North America and Europe using common emissions and boundary conditions for all modeling groups. Roughly twenty modeling groups from both continents participated in this activity. Among the highlights presented are examples of operational, diagnostic, and dynamic model performance that were performed during this phase. We also present the objectives for a new phase of regional model intercomparisons that is coordinated with the ongoing work under the Task Force on Hemispheric Transport of Air Pollution (TF-HTAP) framework. The objectives of this new activity are to evaluate the performance of global, hemispheric and regional modeling systems over Europe and North America and to compare source / receptor relationships simulated through perturbation experiments reflecting emission changes in upwind continents.
