Air District Operations

The Air District is taking steps to ensure Bay Area air quality and public health are protected while the shelter-in-place orders are in effect. Permits for businesses adjusting operations to aid in the public health response will also be expedited. Read more... | en Español

Air Quality Monitoring Map

Air quality data from the sites shown in the map below are available to view online. Pollutants measured include ozone, oxides of nitrogen, carbon monoxide, sulfur dioxide, hydrogen sulfide, particulate matter, hydrocarbons, elemental and organic carbon, and various hazardous air pollutants. Click on a station of interest to view more information about the monitoring site.

Ground-Level Monitoring Map Layer

Ground-level monitors are air quality monitoring stations placed near certain large industrial facilities, such as oil refineries, as required by the facility’s permit. The facility operates the monitoring equipment, but the Air District validates and audits the data collected by the station.

Weather Data Map Layer

Meteorological data from the monitoring sites shown in the map below are available for viewing. Click on a station of interest and a new browser window will open with the site information and files available for download.

Impacted Communities Map

The Community Air Risk Evaluation (CARE) program identifies areas with high concentrations of air pollution and populations most vulnerable to air pollution’s health impacts. The maps, along with information about pollutants and their sources that lead to the impacts, help prioritize a broad array of actions designed to foster healthy communities via the Clean Air Communities Initiative.

Open Burning Map

Open burning is the disposal of any waste material in an open, outdoor fire. Smoke from open burning contains very fine particles, gases, and other toxic chemicals that can be inhaled deeply into the lungs.

To minimize its adverse smoke impacts on public health, open burning is generally prohibited in the Bay Area - with the exception of 17 types of fires that are regulated under the Air District's Open Burning Regulation 5. Certain fires for agricultural purposes, flood control, fire training and the prevention of fire hazards, among other purposes, are allowed when weather conditions are favorable for dispersal and dilution of smoke. Many of these fires are only allowed during specified periods - or burn seasons - throughout the year.

Air Quality Forecast Map

The Air District issues a daily air quality forecast that predicts air pollution levels for the coming five-day period. This forecast uses the U.S. EPA's Air Quality Index scale. For forecasting purposes, cities in the Bay Area have been divided into five reporting zones.
