The ECHO-AIR website documents an open-source modeling tool that converts changes in emissions into estimates of PM2.5 concentration and health impacts using the InMAP Source Receptor Matrix. Developed initially for California, it provides code, setup instructions, and methodological details for running scenario analyses that quantify how incremental emission changes affect population exposure and excess mortality, with an emphasis on environmental justice and climate policy evaluation.
EPA’s Community Multiscale Air Quality (CMAQ) modeling system is an open-source, regional air quality model used to simulate how pollutants such as ozone, PM2.5, and air toxics form and move in the atmosphere. It combines detailed atmospheric chemistry, emissions, and meteorology to estimate pollutant concentrations and deposition over time and space. The CMAQ website provides the model code, documentation, tutorials, input datasets, and example applications, supporting researchers and agencies in evaluating air quality policies, health and ecosystem impacts, and interactions between air quality and climate.
NOAA’s HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory) website provides access to a powerful atmospheric transport and dispersion model used to simulate how airborne pollutants, smoke, dust, volcanic ash, and other particles move and spread in the atmosphere. The site offers model documentation, tutorial materials, downloadable desktop software, and online web-based tools that let users calculate air parcel trajectories, dispersion, and deposition patterns based on meteorological data. It is widely used for air quality studies, emergency response, and research on long-range transport of contaminants.
Mapping tool showing air monitoring locations and the locations that contribute to air quality for a set of large cities in the U.S.
The ARL site is a scientific research and modeling portal. Its mission is to improve the Nation’s ability to protect human and ecosystem health by studying the physical and chemical processes occurring from the soil up to about 2–3 miles in the atmosphere. It is the birthplace of the HYSPLIT model, the global standard for tracking the movement of air parcels.
Air quality maps, trends viewer, a downloadable tool and lab data. From the website: "AQview is a community-focused air quality data portal bringing together government and community-led air monitoring data to a single platform. Our primary goal is make it easier to access, understand, and use air quality data collected from the wide range of monitoring efforts occurring across California."
The AQUA tool is an easy-to-use excel spreadsheet model that city staff can use with minimal guidance. It uses population, exposure, health and economic cost data, as well as epidemiologic evidence to help users calculate how emission changes can benefit local air quality and health.
Atmospheric Composition Analysis Group applies satellite observations, global models, and in situ measurements to improve understanding about the processes controlling air quality, climate, and biogeochemical cycling
