Efforts are underway to plan for a major aerometric data collection, data analysis, and regional modeling program over virtually all of the southern half of the state of California, possibly as early as the summer of 1997. Referred to as the Southern California Air Quality Study, this program has several major objectives including the acquisition of emissions, air quality and meteorological data needed to adapt, evaluate, and apply state-of-science photochemical models to the region. Once refined and evaluated, these models are expected to serve as a framework for ozone and PM-10 control planning in California for the next decade. This paper has two objectives. The first is to summarize ongoing work to adapt the most highly refined, non-proprietary regional air quality, meteorological and emissions models to the SCAQS-97 domain using the August 1987 SCAQS episode as the prototype. The focus of this research activity is to demonstrate the capabilities of these advanced models in designing data collection activities for SCAQS-97 and to identify areas of needed model refinement. Application of sophisticated regional models in advance of the SCAQS-97 field program is an important use of models in that it offers a unique opportunity to test model sensitivities of various data elements so that program resources can be used most cost-effectively. The second objective aims at providing information that may prove useful to states and others faced with the need to develop ozone SIPs.
