The Climate and Environmental Sciences Division (CESD) focuses on advancing a robust predictive understanding of Earth's climate and environmental systems and to inform the development of sustainable solutions to the Nation's energy and environmental challenges. There are five goals which frame the Division's programs and investments: (a) synthesize new process knowledge and innovative computational methods that advance next generation, integrated models of the human-earth system; (b) develop, test and simulate process-level understanding of atmospheric systems and terrestrial ecosystems, extending from bedrock to the top of the vegetative canopy; (c) advance fundamental understanding of coupled biogeochemical processes in complex subsurface environments to enable systems-level prediction and control; (d) enhance the unique capabilities and impacts of the ARM and EMSL scientific user facilities and other BER community resources to advance the frontiers of climate and environmental science; and (e) identify and address science gaps that limit translation of CESD fundamental science into solutions for DOE's most pressing energy and environmental challenges.
