  • US county air-quality exposure intelligence (annual, 2023-2025)

    Annual county-level air-quality exposure panel built from the EPA Air Quality System (AQS) daily AQI-by-county bulk files. Per county and year: reported-day coverage, AQI max/p90, day counts by EPA category, unhealthy-plus (AQI>100) day counts, longest unhealthy streak, Jun-Aug wildfire-season smoke days, dominant pollutant, PM2.5/ozone shares, year-over-year change, a fixed-cut burden tier, and a 0-100 composite burden score. Covers ~990 counties with EPA monitors (50 states + DC). Joins on ISO date + county FIPS for demand-disruption modeling, seasonal staffing, and territory planning.
