Monitoring Methods include: Criteria Pollutants, TO Compendium, IO Compendium, Open Path, and Air Quality Index (AQI). Documents & Articles include: Policy Memoranda/Technical Guidance, Current Articles, and ORD/NERL Documents. Trends & Nonattainment and Regulations are also addressed.
• California Air Quality Data
  The California Air Resources Board (ARB) compiles data from air quality monitoring stations located throughout California. Predefined summaries of annual air quality data are available for Ozone, PM10, and Toxics. The Year-to-Date Ozone includes preliminary 2000 ozone data summaries for the five most populated regions in California and for selected monitoring sites in those regions.The State & Local Air Monitoring Network Plan (NAMS/SLAMS Report) provides the results of the annual review of the air monitoring stations in California. These stations house monitoring instruments that measure ambient levels of gaseous and particulate air pollutants. Move from pollution to monitoring National Atmospheric Deposition Program/National Trends Network (NADP/NTN) A network of monitoring stations for acid rain. Shows concentrations: sulfate, nitrate, ammonium, calcium, magnesium, potassium, sodium, chlorine, and nitrogen ions. Site specific, and some weekly, monthly and daily data. The State & Local Air Monitoring Network Plan (NAMS/SLAMS Report) provides the results of the annual review of the air monitoring stations in California. These stations house monitoring instruments that measure ambient levels of gaseous and particulate air pollutants. The 2001 California Almanac of Emissions and Air Quality is now available in Adobe Acrobat format. Other resources are also available.

• EPA Zip Code Search
  The EPA Zip Code Search offers data on environmental monitoring and environmental conditions by zip code. Enter a ZIP code, then select the type of information you want to find. Zip code information is available on: pollution, hazardous waste sites, and other regulatory information (from Envirofacts); watershed conditions (from Surf Your Watershed); live computer-generated map of regulated sites in zip code (from Enviromapper); and ultraviolet (UV)index forecast (from SunWISE).
