History of tropospheric ozone for the San Bernardino Mountains of Southern California, 1963–1999
AbstractA historical database of hourly O3 concentrations for Crestline, California in 1963–1999 has been developed based on all relevant oxidant/ozone monitoring data taken since 1963. All data were obtained from the California Air Resources Board and the US Department of Agriculture Forest Service and have been standardized to be comparable to the current UV photometry calibration basis. A rigorous statistical analysis was performed to integrate these data with differing accuracies, reliabilities and representativeness of the study site into a temporally consistent research-quality data set for Crestline, California. Records of O3 monitoring on a long-term consistent basis provide much needed information to better understand the chronic effects of pollutants on sensitive species. The database provides valuable information on the changing ambient air quality conditions in the San Bernardino Mountains of Southern California due initially to increases in population and vehicle usage and subsequently due to decreases in O3 precursors from the implementation of more effective emission control strategies beginning in the late 1970s. An Excel spreadsheet containing the hourly O3 concentrations for Crestline in 1963–1999 can be accessed at http://www.epa.gov/wed/pages/models.htm.
