SJVAQS  

Definition

  • 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 &#3617,000,000 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.
