Integrating empirical modeling approaches to improve understanding of terrestrial ecology processes.
Recent decades have seen tremendous increases in the quantity of empirical ecological data collected by individual investigators, as well as through research networks such as FLUXNET (Baldocchi et al. 2001) At the same time, advances in computer technology have facilitated the development and implementation of large and complex land surface and ecological process models. Separately, each of these information streams provides useful, but imperfect information about ecosystems. To develop the best scientific understanding of ecological processes, and most accurately predict how ecosystems may cope with global change, integration of empirical and modeling approaches is necessary. However, true integration in which models inform empirical research, which in turn informs models (Fig. 1) is not yet common in ecological research (Luo et al. 2011) The goal of this workshop, sponsored by the Department of Energy, Office of Science, Biological and Environmental Research (BER) program, was to bring together members of the empirical and modeling communities to exchange ideas and discuss scientific practices for increasing empirical model integration, and to explore infrastructure and/or virtual network needs for institutionalizing empirical model integration (Yiqi Luo, University of Oklahoma, Norman, OK, USA) The workshop included presentations and small group discussions that coveredmore topics ranging from model assisted experimental design to data driven modeling (e.g. benchmarking and data assimilation) to infrastructure needs for empirical model integration. Ultimately, three central questions emerged. How can models be used to inform experiments and observations? How can experimental and observational results be used to inform models? What are effective strategies to promote empirical model integration? less
