Today's Air Quality Maps

OZONE AND PARTICLE POLLUTION

Maps showing the current estimated Air Quality Index (AQI) maps for ground-level ozone are available during the ozone season while current estimated particle AQI maps are available year round. These maps are created by the Air Quality Mapping System from ozone and particle data gathered from a nationwide network of state and local air monitoring stations. The maps show 8-hour average ozone concentrations and 24-hour average particle concentrations in accordance with EPA's Air Quality Index for ozone and particle pollution.
