The Central California Ozone Study (CCOS) is a multi-year program of meteorological and air quality monitoring, emission
inventory development, data analysis, and air quality simulation modeling. Among the goals of this study was the execution
of a large-scale field study in summer 2000 to acquire a comprehensive database to support modeling and data analysis. The
CCOS field measurement program was conducted during a four-month period from 6/1/00 to 9/30/00. Additional data were
collected during ozone episodes (intensive operational periods (IOPs)) to better understand the dynamics and chemistry of the
formation of high ozone concentrations. Measurements of volatile organic compounds (VOCs) as well as actinic flux
measurements were input into a chemical box model employing the Regional Atmospheric Chemistry Mechanism to produce estimates
of hydroxyl (HO) concentrations for CCOS. These estimates of HO were compared with those simulated by a full 3-d air
quality model.
