The TES program will consider applications on measurements, experiments, modeling and synthesis that provide improved quantitative and predictive understanding of the terrestrial ecosystem that can affect atmospheric greenhouse gas concentration changes and thereby affect the greenhouse gas forcing of climate. The emphasis of this FOA is to understand the impacts of, and feedbacks from a changing climate on non-managed terrestrial ecosystems. Authors should pose their research applications in the context of representing terrestrial ecosystem processes in earth system models.
A recent BER workshop outlined science needs for basic research in climate science, including terrestrial ecosystem science as described in the workshop report (http://www.sc.doe.gov/ober/ClimateRoadmapWorkshop_2010.pdf). BER encourages researchers to review this report with particular emphasis on the summary and chapters on ¿Terrestrial Science¿ and ¿Latitudinal Opportunities for Integrated Research Efforts¿ to familiarize themselves with the identified science needs. The goal of the TES program is to provide scientific knowledge of terrestrial ecosystems to (i) provide accurate predictions of their roles in influencing the atmospheric concentration of greenhouse gases; (ii) quantify terrestrial carbon sources and sinks and how they are changing in relation to other atmospheric, climatologic and hydrologic influences; and (iii) assess terrestrial feedbacks on carbon cycle and climate change. Ecosystems are the fundamental unit of research for the TES program. Using modeling and other extrapolation methods, results are expected to extend to bioregion scales, and also contribute to continental scale analysis of carbon cycle problems that are analyzed by the North American Carbon Program (NACP) (http://www.nacarbon.org/nacp/), for example. The TES program will consider applications on measurements, experiments, modeling and synthesis that provide improved quantitative and predictive under
