I am part of a U.S. Forest Service team that has monitored precipitation into and discharge leaving headwater watersheds at the HBEF since 1955. This long-term data set is particularly important in tracking how the water cycle in this forest is responding to changing air quality, vegetation, and climate.
Eric Kelsey, Dan Evans, and I directly measure forest-atmosphere exchanges of water and energy at HBEF with an eddy covariance tower. Data from the tower are providing new insights into controls on forest water use and the implications for forest energy dynamics.
Water dynamics in catchments influences how elements are cycled. I support a number of studies on the role of hydrology in the biogeochemistry of northern temperate forests.
Colleagues and I are studying how forest stands of different composition and management influence microclimates. This involves using novel instrumentation to conduct intensive measurements that help characterize small-scale variabiltiy in water and energy.
I am part of a team working on increasing the use of uncertainty analysis in ecosystem studies. Details about the QUEST project are located here.
