Atmospheric/Air Chemistry

The Department of Meteorology at Penn State University features one of the largest concentrations of faculty and graduate research opportunities on air chemistry and climate change. Field studies are routinely carried out in many regions of the world to investigate trace gas emissions, transport, and deposition in rural and suburban environments. Of particular interest is the transformation of gases to particles and how such particles can directly and indirectly influence climate.

Information obtained from field investigations requires integration within existing numerical models. New numerical models are often developed to study atmospheric transport and chemical transformation of trace gases. Carbon cycle research involves flux tower and numerical modeling studies designed to determine the carbon sequestration provided by forests and agro-ecosystems. Paleoclimate investigations involve data analyses and numerical modeling activities to determine the history and future drivers of the Earth’s climate.

Opportunities are available for graduate students to develop and field-test new instrumentation to study air quality and regional climate change. Numerous possibilities exist for graduate students to become involved with international research in places such as Canada (in the high Arctic), Brazil, Panama, Mexico, Senegal, and South Africa.
