State and Local Air Monitoring Network Plan

This page last reviewed on July 2, 2009

The State and Local Air Monitoring Network Plan provides a wealth of information about ambient air quality monitoring sites in California and the Tijuana and Mexicali areas of Mexico. The monitoring sites in the network include instruments that measure ambient levels of gaseous and particulate air pollutants, and in some cases, meteorological parameters. A separate report, i.e., the Annual Monitoring Network Report, lists additional information for some of the smaller air districts in California. Table 1 below includes the range of years for which fully reviewed air quality data are available for each pollutant at each site. Table 1 also indicates whether real-time data are available for a monitor. Table 2 includes more specific characteristics of the criteria pollutant monitors at each site. Table 2 also includes the range of years of meteorological data available and the latitude, longitude, and elevation of each site. Maps indicate the locations of monitoring sites within each air basin in California.
