Air quality trends and historical information.

Table lists standards for six principal pollutants: carbon dioxide, sulfur dioxide, carbon monoxide, lead, particulates, ozone. Each pollutant has a link that leads to a page detailing its emission sources (at national, state, and local levels), and more.

Compare air quality in up to 3 states or up to 10 counties in one state of multiple states.

See link to Excel chart: "1970-2012 Average annual emissions." Each xls sheet has data from specific pollutant; e.g., NOX breaks down data into fuel type, vehicles, waste disposal, etc. From EPA's National Emissions Inventory.

Cap-and-trade and other market-based air programs. Under Data & Maps, see Air Market Program Data: maps and reports on top emitters, an xls chart of state emissions in 3 pollutants, according to what criteria you choose.

Starting point for links to CA emissions data (by source, by region, etc.), types of emissions, health effects of emissions, and more.

Page not updated since 2009, but look for the link to current Ambient Air Quality Standards Chart (pdf), which lists 11 pollutants and compares CA and national standards. Each pollutant has a link to more detailed information, such as concentrations over time.

Cal-Adapt has been designed to provide access the wealth of data and information that has been, and continues to be, produced by the State's scientific and research community. The data available in this site offer a view of how climate change might affect California at the local level. Here you can work with visualization tools, access data, and participate in community sharing to contribute your own knowledge.

This NASA site's key indicators include CO2 concentration, surface temperature, sea ice, land ice, and sea level, typically displayed as graphs and in graphic metrics.
