Air Modeling - Reports and Journal Articles

The EPA conducts modeling analyses to support policy and regulatory decisions and also coordinates with others in the modeling community on the development of new models and techniques. This section of the website provides reports as well as a bibliographic listing of journal articles they have authored or co-authored by technical EPA modeling staff.

Reports are available for download in PDF format by clicking on the title of the report. Journal articles may be retrieved at various online libraries for a fee or at libraries that carry the journal.
