Point location layers and supporting documentation for the EPA Interactive Map of Air Quality Monitors, extracted in March 2026. The data includes monitor locations for criteria pollutants (CO, Pb, NO2, Ozone, PM10, PM2.5, SO2) and specialized networks like IMPROVE and NATTS. The United States Environmental Protection Agency is the authoritative source.
Use Cases
- Mapping air quality monitor locations based on the described point location layers.
- Analyzing the distribution of monitoring stations for criteria pollutants.
- Identifying monitor networks like IMPROVE and NATTS for specialized air quality studies.
- Accessing daily and annual summary data via the download links included in the point layers.
Strengths
- Includes monitor locations for all seven criteria pollutants.
- Covers multiple specialized monitoring networks such as IMPROVE, NATTS, NCORE, and PAMS.
- Point layers include fields with HTML links for downloading annual and daily data.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; the description references a quote from March 2026.
