US Clean Air Status and Trends Network

Using the Clean Air Status and Trends Network (CASTNET) data released by the Environmental Protection Agency, this map shows the ozone levels across the U.S.  By clicking on a dot, users can view detailed information about the ozone measurements for that area over time. The faceted browsing in this demo uses the Exhibit framework developed by the Simile Project at MIT.
