DOE research seeks to understand basic chemical, physical, and biological
processes of the earthís atmosphere, land, and oceans and how these processes
may be affected by energy production and use, primarily the emission of carbon
dioxide from fossil fuel combustion.
Understanding global climate change and the
ability to predict climate over decades or centuries will enable the development
of science-based solutions to reduce and minimize the impacts of climate change
and better plan for the nationís future energy needs.
An international team of researchers from Oak Ridge National Laboratory, Macquarie University, the University of Western Sydney and the Max Planck Institute for Biogeochemistry set out to assess how two Free-Air CO2 Enrichment projects compared to eleven vegetation models that simulate various ecological processes. Instead of only benchmarking whether or not an individual model matched the experimental data, the researchers developed an 'assumption-centered' approach to evaluate why certain models performed better than others.
With two off-the-shelf digital cameras situated about 1 kilometer apart facing Miami's Biscayne Bay, Berkeley Lab scientists David Romps and Rusen Oktem are collecting three-dimensional data on cloud behavior that have never been possible to collect before.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
