County-Level Attainment Status for National Air Quality Standards

County-level records detail the attainment status of U.S. counties for National Ambient Air Quality Standards (NAAQS). The dataset tracks statuses for pollutants like ozone and nitrogen, with updates provided by the New York State government. Multiple platforms list the most recent update as April 2026, indicating a forward-looking maintenance schedule.

Use Cases

• Analyzing regional compliance trends using the YEAR, STATE, and ATTAINMENT STATUS columns.
• Mapping pollution-specific non-attainment areas using the NAAQS POLLUTANT and COUNTY fields.
• Studying the evolution of air quality standards over time with the NAAQS STANDARD and NAAQS LEVEL AND AVERAGING TIME columns.

Strengths

• Provides a specific, standardized set of seven columns detailing pollutant, standard, status, and location.
• Maintained with a documented update schedule, evidenced by a listed 'last updated' date of 2026-04-04.
• Available in multiple structured formats (CSV, JSON, XML, RDF) supporting diverse technical workflows.

Limitations

• Key quantitative metrics like total row count, dataset size, and precise temporal coverage are unavailable across all sources.
• The listed 'last updated' date of April 2026 is in the future, creating uncertainty about the actual data freshness.
• License and author information is not provided, limiting clarity on reuse permissions and original provenance.
