The research in Climate and Earth System Modeling provides the foundation for developing a predictive understanding of interactions between energy activities and Earth system changes. The Department of Energy (DOE) PI meetings, where scientists present their results to the larger community working in the field, are essential to progress in the field, to encourage and establish efficient collaborative activities, and to align the community's research with the Department's mission needs.

The Biological and Environmental Research (BER) Program's Climate and Earth System Modeling Program hosts an annual meeting of all the funded PIs (grantees and National Laboratory contractors) within the program. These annual meetings are critical to fostering discussion of the latest research results and developing new ideas for Earth system model development and analysis, including the integration of human and climate systems, and the integration of the terrestrial, atmospheric, cryospheric, oceanic systems and processes into a regional or global coupled model; and the improvement of computational efficiency and tools to analyze and visualize models and measurements. The meetings are attended by inter- and intra-agency partners [including National Oceanographic and Atmospheric Administration (NOAA), National Aeronautics and Space Agency (NASA), National Science Foundation (NSF), and Environmental Protection Agency (EPA)] and international researchers furthering scientific exchange and programmatic coordination. This four day meeting is structured to maximize presentation, discussion and integration of a wide range of the topics. Selected investigators from within and external to the program are invited to offer scientific presentations in morning plenary sessions while continued discussion of focused topics continues in a variety of breakout sessions throughout the afternoon. Science discussion continues during evening poster sessions.
