Oak
Ridge National Laboratory (ORNL) researchers are partnering with other
Department of Energy (DOE) laboratories to improve the supercomputing
applications that deliver breakthroughs in climate science.
Forrest Hoffman, Kate Evans, James Hack, and other scientists at ORNL’s Climate Change Science Institute participate in three projects funded through the Scientific Discovery through Advanced Computing, or SciDAC, Program. These projects aim to improve the Community Earth System Model, a megamodel that couples interactive component models of the atmosphere, ocean, land, and sea and land ice. ORNL scientists are integrating multiscale algorithms to better simulate atmospheric and oceanic phenomena, verifying the accuracy of ice sheet simulations, and improving the representation of biogeochemical cycles on land and in the ocean and atmosphere. These researchers and dozens of others run Earth system models on the Oak Ridge Leadership Computing Facility’s Titan supercomputer.

“These projects are designed to advance the simulation and predictive capabilities of the models,” said Hoffman, one of the SciDAC principal investigators. “These projects partner climate scientists, mathematicians, and computer scientists to improve the accuracy and scientific fidelity of these complex models and to deliver a new generation of Earth system models with unsurpassed performance on the leadership class computing facilities that DOE operates.”
Hoffman attended the SciDAC-3 Program meeting in Rockville, Maryland, July 24–26. The annual meeting assembles lead investigators and collaborators in math, computer science, and a variety of scientific fields to coordinate computational research that fosters new discoveries.—by Jennifer Broun Posted 11/25/2013 4:15 p.m.
