Technical Report on Ozone Exposure, Risk, and Impact Assessments for Vegetation

Documentation and a user's guide for ozone exposure, risk and impact assessments for vegetation completed in 2007.

Code files and input data files used in the analyses

The User’s Guide DVD provides the actual code files and input data files used in the analysis.  Because many of the data files are extremely large, they are not available for interactive download. To receive a DVD containing all of the code and data files, contact Vicki Sandiford via email at sandiford.vicki@epa.gov.

You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
