The
California Air Resources Board (ARB) gathers air quality data for the
State of California, ensures the quality of this data, designs and
implements air models, and sets ambient air quality standards for
the state. ARB compiles the state's emissions inventory and
performs air quality and emissions inventory special studies.
The Air Quality Data page provides access to ambient air
quality data, maps of areas that violate the national and state
air quality standards, and maps of the ambient air quality
monitoring network.
The ARB uses the Emissions
Inventory and Air Quality Models to evaluate air quality and reduce
emissions in each of the 35 local air districts.

Quality Data |
The main page for
data, statistics and other information on
California’s air quality. |
| Today's Air Quality
|
The AQMIS2 web
page
provides access to near real time air quality data for California. This
page provides links to other products including week-at-a-glance
statistics and hourly air quality data. |
| Air Quality Data Statistics
|
The iADAM web page
lets you see historical summaries indicating how good or bad the air
quality is throughout California for a number of pollutants. For
example, you can view the number of days per year that air quality is
deemed to be unhealthy, and how this has changed over the years. Toxics
data summaries are also available. |
| Air Quality Monitoring Network
|
Here you will find
a listing of the air quality monitoring sites in California and what
pollutants are monitored at each site. Tables indicate how many years
of data are available for each site. Includes maps of the site
locations. |
| Standards and Designations
|
The ARB designates
areas of California for each criteria pollutant based on recent ambient
air quality data. The Area Designations provides information regarding
the designation areas in California with respect to the State Ambient
Air Quality Standards. Areas can be designated as attainment,
nonattainement, or unclassified. |
| Current Air Quality Standards
|
This page
describes
California’s ambient air quality standards currently in
effect. |
| Standards Under Review
|
This page provides
information about the current review of California ambient air
quality standards mandated by the Children's Environmental Health
Protection Act (CEHPA, Senate Bill 25,
Escutia, 1999) |
| Air Quality Index (AQI)
|
The U.S. EPA's Air
Quality Index (AQI) provides accurate, timely and easily understandable
information about daily levels of air pollution. |
| Emission Inventory
|
An emission
inventory is an estimation of air pollution that helps us answer
questions about what pollutants are being emitted, how much is being
emitted, and where they are coming from. |
| Air Quality Models
|
Air quality
modeling software and associated documentation. |
| Southern California Studies
