Understand air quality impacts on regional and national scales. STI uses EPA-accepted models such as CMAQ and CAMx to evaluate air quality for single-source impact assessments, state implementation plan (SIP) development, exceptional event demonstrations, and policy analyses.
Conduct meteorological modeling to inform forecasting, develop inputs for air quality models, and understand how meteorological conditions influence pollutant chemistry and transport. Using models such as the Weather Research and Forecasting Model (WRF), we work with clients to evaluate source-receptor relationships, improve meteorological outputs through targeted observations and data assimilation, and support alternative energy applications.
Air Dispersion Modeling
Evaluate the near-field air quality impacts from stationary sources and transportation projects. STI scientists use a variety of dispersion models, including AERMOD, CALINE, and R-LINE, to help our clients conduct research and perform human health assessments and PM hot-spot analyses.
