Sector: Energy generation
Refined dispersion models listed in the Guideline of Air Quality Models and required to be used for State Implementation Plan (SIP) revisions for existing sources and for New Source Review (NSR) and Prevention of Significant Deterioration (PSD) programs.
US EPA National Emissions Inventory data collected for point, area and mobile sources
The Air Quality Life Index (AQLI) converts air pollution concentrations into their impact on life expectancy. Through the AQLI’s hyper-local data, users anywhere on Earth can zoom into their district and see how much longer they would live if policies were to reduce pollution to meet the World Health Organization’s guideline, a national standard, or a user-defined target. This information can help inform local communities and policymakers about the benefits of air pollution policies in perhaps the most important measure that exists: longer lives.
Benefits of reducing PM and ozone precursors on a per-ton basis
The Air Quality System (AQS) contains ambient air pollution data collected by EPA, state, local, and tribal air pollution control agencies from over thousands of monitors. AQS also contains meteorological data, descriptive information about each monitoring station (including its geographic location and its operator), and data quality assurance/quality control information.
Real TIme Geospatial Data Viewer (RETIGO) is a free, web-based tool that can be used to explore environmental data that you have collected either stationary or in motion (e.g., air quality sensors added to a bike).
CALPUFF is an advanced non-steady-state meteorological and air quality modeling system. It is maintained and distributed by Lakes Environmental.
This resource, managed by the EPA Office of Congressional and Intergovernmental Relations (OCIR), serves as the primary gateway for state, local, and tribal officials to navigate federal environmental resources, funding, and collaboration frameworks
The Tropospheric Emissions: Monitoring of Pollution (TEMPO) Nitrogen Dioxide Vertical Column Troposphere Provisional layer provides information on the amount of nitrogen dioxide in the troposphere, available as approximately one-hour scans for daylight hours over North America, from August 2023 to September 2025. These data should be considered as provisional products, which are potentially ready for testing by operational users and may be suitable for scientific publication. The data is obtained from NASA's Atmospheric Science Data Center (ASDC) .
