The Air We Breathe — Live

Clean spots, dirty spots and the carbon in the sky, updated from free open sources

Live air-quality readings for over seventy world cities, modelled by the Copernicus Atmosphere Monitoring Service and delivered through the free Open-Meteo API, refreshed on our side every 45 minutes. These are model estimates for each city’s coordinates — your street can differ; treat them as a global pulse, not a personal sensor. Weather for any of these cities lives at World Weather.

Reading the scale (US AQI)

Number	What it means
0–50	30 · Good — air quality satisfactory for everyone.
51–100	75 · Moderate — acceptable; unusually sensitive people should mind long outdoor effort.
101–150	130 · Sensitive groups — children, older adults and lung/heart conditions feel it first.
151–200	170 · Unhealthy — everyone starts to notice; sensitive groups clearly affected.
201–300	250 · Very unhealthy — health effects likely; postpone hard outdoor exercise.
301+	350 · Hazardous — emergency conditions; nearly everyone is affected.
