The California Air Resources Board's air quality monitoring program collects accurate real-time
measurements of ambient level pollutants at over 40 sites located throughout the state. The data generated are
used to define the nature and severity of pollution in California; determine which areas of California are in attainment
or non-attainment; identify pollution trends in the state; support agricultural burn forecasting; and develop air
models and emission inventories.
The program encompasses operation of the sampling and monitoring network, laboratory analysis
of air samples, and quality assurance activities to ensure the quality of the data collected and disseminated by
the ARB and the local Air Quality Management and Air Pollution Control Districts. In addition, technical assistance
is provided to local air quality districts and others active in air pollution programs.
For more detailed information on the specific air quality monitoring programs, refer to

about quality assurance activities conducted by the Air Resources Board
(ARB). The ARB supports and conducts appropriate quality
assurance activities to ensure that data collected is in compliance
with procedures and regulations set forth by the U.S. EPA and can be
considered good quality data and data-for-record.
