Why WildfireWindow is accurate
Most AQI sites still use the pre-2024 breakpoints and show a raw hourly reading. During fast-moving smoke that disagrees with the official number. We use the 2024 EPA breakpoints and AirNow's NowCast method, and for US monitors we show AirNow's reported AQI as the display truth.
