About this data
AQI from EPA AirNow monitors, and where none is close, the nearest EPA-corrected PurpleAir community sensor (labeled as an estimate). Refreshed through the day. Managed by U.S. Fish & Wildlife Service. Wind from Open-Meteo. Fire data from NIFC WFIGS. Smoke analysis from NOAA HMS. Boundaries from USGS PAD-US 4.0. Where no sensor is anywhere near, we say so rather than guess.
