Air Quality Measurements
Air Quality Data Analysis
Develop a greater understanding of the real-world air quality impacts of your projects. STI has extensive experience working with clients to determine project objectives and performing detailed analyses to meet these objectives. We assess air quality at national, regional, and local levels, including in Environmental Justice communities.
Data Validation and Analysis
Understand the implications of your data using our proven data analysis techniques and in-house, customized tools. STI uses state-of-the-science analysis, statistical, and visualization platforms to assess and communicate ambient air quality data.
Reliably assess your source impacts; STI scientists are leading experts in source apportionment, receptor modeling analysis, and modeling tool development. STI develops comprehensive pre- and post-apportionment analysis using the latest statistical applications and models.
Compliance and Data Analysis Support
Solve your compliance and data analysis issues; our proven track record with both industrial clients and regulatory agencies allows us to help clients better understand and navigate the regulatory environment.
Develop your data analysis skills through customized training courses that fit your needs and knowledge levels. Training topics span all STI business areas and leverage our expertise across multiple disciplines.

Kids Making Sense Education Outreach
Kids Making Sense® is an exciting environmental education program that teaches students about air quality and how to measure air pollution using hand-held sensors and mobile phones, empowering them to drive for positive change in their communities. Visit kidsmakingsense.org.
Students participate in hands-on science tasks, discuss their findings with an air quality scientist, and share their data with the global air quality community.
They can even use their data to identify local sources of air pollution and take actions to be part of the solution.
Developed by air quality scientists and educators, and thoroughly tested with teachers and students around the world, Kids Making Sense unites STEM (Science, Technology, Engineering, and Math) education and NGSS (Next Generation Science Standards) with an air sensing system.
Grow Local Awareness and Support
Educate youth about air pollution at a time when they are forming their driving and consumption behaviors.
Increase awareness of your air quality mission among residents who follow science, education, environmental, and public health news. We have conducted Kids Making Sense events across the country, including in schools located in Environmental Justice communities.
Air Quality Instrumentation
Air Quality Forecasting
Emissions Assessment and Air Quality Modeling
Use STI’s expertise to design comprehensive air quality and exposure studies and evaluate emission control strategies. We develop highly resolved emissions inventories for criteria pollutants, greenhouse gases, and air toxics for use in modeling and management planning. We use air quality and meteorological modeling to inform forecasting, assess emissions source impacts, and support control measure assessments and other air quality management decisions.
Emissions Inventory Development
Have confidence in your emissions estimates. STI prepares high-quality emissions inventories and improves existing emissions assessments by collecting emission factors and representative activity data for a variety of source types.
Rely on our expertise to perform meteorological, emissions, and photochemical modeling to understand air quality impacts on regional and national scales. Using EPA-approved models, we work with clients to evaluate air quality for single-source impact assessments, SIP development, exceptional event demonstrations, and policy analyses.
Prepare emissions data for air quality modeling or other analyses using the latest modeling tools, including MOVES, EMFAC, BEIS, and SMOKE.
Air Dispersion Modeling
Evaluate the near-field air quality impacts from stationary sources and transportation projects. We use a variety of dispersion models to help our clients perform human health assessments, conduct PM hot-spot analyses, and evaluate air quality in Environmental Justice communities.
