Advanced Modeling of Air Quality

The Holloway Group at SAGE has over 20 years experience modeling weather, climate, emissions and air quality using state-of-the-art methods. We specialize in regional to continental scale simulation over the U.S., with a focus on win-win solutions of energy, air, health and climate. Primary modeling tools include the WRF (Weather Research and Forecasting Model), CMAQ (Community Multiscale Air Quality Model), BenMAP (Environmental Benefits Mapping and Analysis Program) and MEGAN (Model of Emissions of Gases and Aerosols from Nature) models. We also link our work with energy system models (e.g. MyPower, EPA AVERT, GridView), and transportation models (especially MOVES). We also regularly analyze model results from collaborating organizations, including the U.S. EPA.
