As the air pollution control
agency for all of Orange County and the urban portions of Los Angeles,
Riverside and San Bernardino Counties, the AQMD collects data on current air
quality, provides forecasts and analyzes trends in levels of pollutants. In
addition, AQMD staff models and provides data for specific projects.
Current data is available in
several different ways. The current hourly data is available in text form at
“Current Readings (Text)” or by using
a map at “Current Readings (Clickable
Map)”. Animated maps showing AQMD ozone (May-October) and Particulate
Matter levels and forecasts are also available through the EPA AIRNow
website at "Animated
Air Quality Map"
The "Daily
Air Quality Forecast" page shows the current forecast, which is updated
on a daily basis. A color version of the air quality forecast in terms of
Air Quality Index (AQI) that is sent to schools, parks and recreational
facilities is also available at “Air Quality Forecast (AQI)”. Tomorrow’s
forecast is typically available by noon each day. A description of the AQI
levels and AQMD recommended cautionary statements can be found at
Air Quality Index.pdf.
Air Quality data, trends and
special studies are available via the Air Quality Data
page. In addition, the California
Air Resources Board has current and historic data for AQMD and many
other areas in California. If
