Support your air quality management needs with state-of-the-science modeling and analysis solutions.
STI’s scientists apply the latest modeling, analysis, and visualization software and methods to meet air quality management, planning, and decision support needs. Our modeling work covers local-to-hemispheric scales and includes multi-pollutant impact assessments, exceptional event demonstrations, policy analysis, permitting and compliance efforts, and the development of real-time modeling systems.

Understand air quality impacts on regional and national scales. STI uses EPA-approved models such as CMAQ and CAMx to support state implementation plan (SIP) development, exceptional event demonstrations, policy analyses, and air quality impact assessments for a variety of sources.
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.
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.
Understand the fate and transport of pollution from stationary sources to support air quality management planning, meet compliance needs, and mitigate impacts on public health.
Understand how travel activity, meteorology, and other factors contribute to near-road air pollution, and evaluate real-world impacts of on-road mobile sources.
