Topic: Air quality data
Document describing methods used to evaluate air quality impacts of the Central Business District Tolling Program in New York City.
MiEJScreen is a screening tool that provided percentile scoring various environmental, health and socioeconomic indicators to measure relative environmental risk in communities. This map is meant for general information about Environmental Justice in Michigan and is a collection of basic data sets related to Environmental Justice concerns which allow users to identify, query, and filter the data.
NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) project page at the Atmospheric Science Data Center provides access to data and documentation for the TEMPO instrument, a UV–visible grating spectrometer in geostationary orbit that measures key air pollutants over North America. From its fixed position above 91°W, TEMPO scans the continent hourly during daylight, using reflected sunlight to retrieve ozone, nitrogen dioxide, formaldehyde, aerosols, and related atmospheric constituents that are critical for understanding air quality and its impacts. The site offers mission descriptions, data product access (Level 1–3), user guides, and algorithm documents to support research, forecasting, and applications in health and environmental management.
The HARP Air Dispersion Modeling and Risk Tool, developed by the California Air Resources Board, is Windows-based software that allows users to run air dispersion models and calculate associated health risks from toxic air pollutants. Used primarily in the state’s Hot Spots Analysis & Reporting Program, it integrates modeled concentration outputs with built?in health effect values and demographic data (including a dedicated census database and health database) to support standardized health risk assessments for stationary emission sources in California.
The CACES data portal provides publicly available, high?resolution estimates of air pollution exposures and related metrics developed by the Center for Air, Climate, and Energy Solutions. It offers gridded and geographically linked datasets (e.g., by census tract, county, or other units) for pollutants like fine particulate matter (PM?.?), ozone, and nitrogen dioxide over multiple years, along with documentation and code. Researchers, agencies, and advocates can download these modeled exposure surfaces to analyze trends, assess health and equity impacts, and link air quality estimates to demographic, health, and policy data.
Interactive map that displays information on air quality monitoring, locations of oil and gas wells, ozone and PM2.5 nonattainment areas, permitting and compliance for NSR and Title V permits, and point source emissions.
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.
Report on air pollution impacts from NYC Congestion Relief Zone. Provides data from real-time air quality monitoring inside and outside the zone.
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.
