Andrew Oliphant's research investigates interactions between Earth's surface and its atmosphere, including exchanges of energy, water and carbon, and how they change over space and time. His research methods primarily involve field-based observations using micrometeorological instruments mounted on towers above the surface and has included a diverse range of field sites from the Antarctic Dry Valleys to a central Iranian desert, although has primarily focused on terrestrial ecosystems. Most of this work has focused on a carbon flux tower site in the Morgan-Monroe State Forest in south-central Indiana. However, Andrew is currently working on a synthesis study using the FLUXNET database of approximately 400 carbon flux tower sites over a range of terrestrial ecosystems around the world. The focus of this research is the role of changing sky conditions on global terrestrial carbon sequestration. With the recent acquirement of a mobile atmospheric profiling system (CSU-MAPS), Andrew participated in an experiment on prolonged temperature inversions in Salt Lake City Basin and the role they have on air pollution dispersion (PCAPS) and looks forward to future collaborative projects that provide observational evidence for surface-atmosphere exchange processes, including over San Francisco and other urban surfaces.
