Method & caveats. Pollutant-specific worksheet, Total without wildfires row, annual year columns. EPA's own estimates throughout: EPA publishes no PM2.5 total without wildfires before 2002, so this line begins in 2002; 2002–2019 EQUATES-modeled, and the years after the latest full NEI (2020 onward) interpolated or projected by EPA; no interpolation performed here. EQUATES-modeled 2002–2019; 2020–2025 are EPA interpolated or projected estimates pending the next full inventory. Breaks: EQUATES-modeled 2002–2019; 2020–2025 are EPA interpolated or projected estimates pending the next full inventory.
