San Joaquin Valley Air Quality Study

Project Description
The San Joaquin Valley Air Quality Study (SJVAQS)was performed by the
California Air Resources Board and various other public agencies,
private organizations, and universities. Sponsors included the
U.S. EPA, California Air Resources Board, Pacific Gas and Electric
Company. The study begin in 1986. There was ม,000,000 in
funding for this project.

The SJVAQS is the core of these collaborative studies. The goals of
the SJVAQS are twofold: (1) provide an improved understanding of the
types of conditions that lead to high ozone concentrations in the
Valley, and (2) provide decision-makers with the information needed to
develop sound regional plans for equitable and effective emissions
controls.

The technical objectives include:

Characterizing Valley meteorology, the temporal and spatial patterns
and frequencies of ozone and precursor concentrations within the
Valley and surrounding areas,

Characterizing pollutant fluxes of ozone and precursors at locations
entering and leaving the Valley,

Characterizing the temporal and spatial distribution and amounts of
emissions from anthropogenic, biogenic, and geogenic sources,

Developing source-receptor relationships to improve understanding of
transport and atmospheric processes influencing air quality in the
Valley, and

Developing and specifying modeling and data analysis approaches for
relating emissions and air quality.
