Earth and Environmental Systems Institute

The Earth and Environmental Systems Institute (EESI) is the portal to environmental research, education, and outreach programs offered by the College of Earth and Mineral Sciences and is one of the leading earth and environmental sciences research institutes in the U.S. EESI is affiliated with Penn State's Institutes of Energy and the Environment (IEE), the central coordinating structure for energy and environmental research, education, and outreach at Penn State.


EESI's mission is comprised of four interrelated elements:

  • To encourage interdisciplinary examination of the links between Earth’s chemical, physical, and biological processes from atomic to global scales by supporting faculty and student research on earth sciences and environmental issues;
  • To facilitate the modeling and manipulation of data in new and innovative ways through EESI’s Environmental Computing Facility;
  • To facilitate dissemination of research findings through publications, presentations, web pages, workshops, seminars, testimony to public agencies, and advice to public and private organizations and agencies; and
  • To develop innovative, interdisciplinary research and education programs that benefit internal and external stakeholders, including the Penn State community, the Commonwealth, scientific communities, and federal and state science agencies and organizations.

Study sheds new light on forests' response to atmospheric pollution

How forests respond to elevated nitrogen levels from atmospheric pollution is not always the same. While a forest is filtering nitrogen as expected, a higher percentage than previously seen is leaving the system again as the potent greenhouse gas nitrous oxide, say researchers.
