Air Quality Index vs AirGradient Map

Air Quality shows you what is actually in the air — where the smoke is, where it is heading, and what the air is like at any point on Earth you tap. See the smoke before it arrives A 48-hour NOAA HRRR forecast for the continental US and Alaska, hour by hour, at ground level and through the whole air column. Scrub the timeline and watch a plume move. Outside the US, Copernicus CAMS gives you five days of global smoke, dust, and haze. Air quality across a whole country, not a scatter of dots The US air quality map draws the hourly AQI as a continuous field from EPA AirNow, with a second layer for tomorrow’s forecast. Monitor readings ride on top as pins you can tap. Community sensor readings from OpenAQ cover the rest of the world. A forecast anywhere, not just where a weather station is Tap or press and hold any point on the map for a five-day air quality forecast — a stretch of coastline, a trailhead, a valley with nobody in it. Layers you choose • Ground-level and column smoke, 48 hours (NOAA HRRR) • Global smoke, dust, haze, PM2.5 and aerosol, 5 days (Copernicus CAMS) • US air quality index, now and tomorrow (EPA AirNow) • EPA monitor readings and worldwide community sensors • Active wildfires and satellite heat detections (NASA EONET, NASA FIRMS) • Daily satellite photography (NASA GIBS) • Volcanoes (Smithsonian Global Volcanism Program) • Pollen forecasts for six species across Europe On every screen you own Widgets and complications for a glance. An Apple Watch app with the reading and a five-day chart. An interactive 3D globe on Apple Vision Pro. An ambient satellite flyover on Apple TV. Multiple windows, a sidebar and a menu bar item on Mac. Free and private No price, no subscriptions, no ads, no accounts. Your location is used to show you the air where you are and never leaves your device.
