The Toxics Release Inventory (TRI) Program tracks the industrial management of toxic chemicals. TRI data are reported annually by industrial and federal facilities that meet reporting requirements. EPA makes these data available through multiple online tools, many of which add context to help make the reported data more understandable.
The Remote Sensing Information Gateway (RSIG) allows for quick and easy access to subsets of multi-terabyte environmental datasets pertaining to air quality, including satellite, modeled, and in-situ sensor data. RSIG can tap into a wide range of key environmental models and data, such as NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS), the Environmental Protection Agency’s (EPA) Community Multi-scale Air Quality (CMAQ) model output, National Environmental Satellite, Data, and Information Service (NESDIS) biomass burning data, and ground station measurements from AIRNow and EPA’s Air Quality System (AQS). RSIG also enables users to integrate their selected datasets into a unified visualization.
RSIG renders each dataset and overlays them on a map of the selected region, automatically aligning information from various spatial and temporal scales into a unified visualization.
Online repository of air quality data and metadata sponsored by the National Park Service and the U.S. Forest Service. FED has been developed to help states, tribes, federal land managers (FLMs), scientists, planners, and students evaluate air quality and visibility in federally-protected ecosystems using a variety of national and regional air quality datasets.
Provides a Python script to create wind rose and pollution rose plots for PM2.5 using pollutant, wind speed, and wind direction data.
This is a website tool that provides access to real time and historical PM2.5 data obtained from an air sensor network comprised of IQAir sensors.
Website tool that helps users find walking or cycling routes to reduce exposures to NO2 and PM2.5.
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.
AQMx is the Air Quality Management Exchange Platform, an online “one?stop shop” designed to build capacity among air quality managers worldwide. Led by the Climate and Clean Air Coalition and UNEP, it provides curated guidance, technical tools and models, data resources, and case studies covering core aspects of air quality management—such as monitoring, emissions inventories, source attribution, health impact assessment, legal frameworks, and sector?specific mitigation in areas like transport, household energy, agriculture, and waste. The platform is aimed especially at low? and middle?income countries and is structured to help governments and practitioners design and implement strategies to meet WHO Air Quality Guidelines and interim targets.
The toxic flooding vulnerability map is an interactive tool that ranks and visualizes how vulnerable petrochemical facilities and nearby communities in the Galveston Bay region are to toxic flooding. Built from more than 100 indicators across flood risk, chemical transport, facility hazards, ecosystem conditions, baseline health, and social and economic factors, it produces separate vulnerability scores for facilities and for community grid cells. Users—such as planners, engineers, policymakers, and Gulf Coast residents—can explore overall vulnerability, drill down to see which specific indicators drive risk in each location, identify high?priority facilities and neighborhoods, and use downloadable profiles and map layers to help target nature?based solutions that reduce both flooding and chemical exposure.
Mapping tool showing air monitoring locations and the locations that contribute to air quality for a set of large cities in the U.S.
