The five pollutants included areozone, particulate matter (PM2.5), carbon monoxide (CO), nitrogendioxide (NO2), and sulfur dioxide (SO2). The statistics are the sameas those presented in Chapter 4 with the addition of CO, and thetime period covered is 1992 through 2011, for PM2.5. the time periodis 1999 to 2011.Air quality statistics can fluctuate from year-to-year because of theinfluence of meteorology and/or changes in emissions. However, thestatistics can also vary because of a change in monitoring site. Thedesign value and maximum value statistics listed here reflect thehighest value for the statistic at any site in the area. As a result, thestatistic may not reflect the same site during the entire trend period.For example, the maximum 8-hour CO concentrations in ImperialCounty in the Salton Sea Air Basin were below the level of thenational standard from 1992 through 1993. In 1994, however, theconcentration shows a significant increase, and the national standardwas violated. The CO concentrations in the Salton Sea Air Basin didnot suddenly increase during 1994. Instead, monitoring began at anew site in Calexico, and the concentrations at the new site werehigher than at the existing sites in the air basin. Information aboutthe time periods for which air quality data are available for differentpollutants at sites in California and Baja, Mexico is available onlineatwww.arb.ca.gov/adam/netrpt/.Since the design value and maximum air quality statistics reflect thehighest values in the area, the monitoring sites represented also maynot be consistent among the various statistics during a particular year.For example, the monitoring site reflected in the maximum 1-hourozone concentration may not be the same as the monitoring sitereflected in the maximum 4th high 8-hour ozone concentration.In contrast to the peak and maximum statistics, the counts of daysabove a standard reflect composite, basinwide values (i.e. a count ofthe total number of days an exceedance occurred at any site in theair basin).File 07 App A Alm2013 p1-18.indd 512/16/2013 10:31:39 AMARB Almanac 2013 – Appendix A: Air Quality Trend Data by Pollutant: Ozone, PM2.5, CO, NO2, SO2A-6Appendix AAppendix AOzoneAnnual
