Dakota Version 5.4 Released

Sandia’s Dakota software delivers advanced parametric analysis techniques enabling design exploration, model calibration, risk analysis, and quantification of margins and uncertainty with computational models. Dakota v5.4 was released November 15, 2013, and deployed on supported Sandia computing systems. The release includes new capabilities for uncertainty quantification (UQ), optimization, and calibration. UQ highlights include a new […]

Sandian Mark Boslough Featured on NOVA Episode about Chelyabinsk Meteor

On February 15th, a 7,000 ton asteroid crashed into the Earth’s atmosphere, exploded, and fell to the ground in the Ural Mountains near Chelyabinsk, Russia. According to NASA, the meteor exploded with the power of 30 Hiroshima bombs and was the largest object to burst in the atmosphere since the Tunguska event of 1908—another Siberian […]

Louisiana Blue Ribbon Commission on Bayou Corne Safety

Secretary Stephen Chustz, from the Louisiana Department of Natural Resources (LADNR), asked David Borns (in Sandia’s Geotechnology and Engineering Dept.) to serve on the blue ribbon commission (BRC) that was formed by Governor Bobby Jindal to provide science-based public safety recommendations regarding the sinkhole in the Bayou Corne area. The BRC will help LADNR continue […]

Implemented “Vertically Lagrangian” Option in the Community Atmosphere Model

The Community Earth System Model (CESM) is a state-of-the-art global climate model being developed with the support of the National Science Foundation and the Department of Energy and used for climate-change science and assessments. Sandia has been leading a multilaboratory effort to develop a new “dynamical core” for CESM’s atmospheric component. This new dynamical core […]

CRF Researchers Measure Reaction Rates of Second Key Atmospheric Component

Researchers at Sandia’s Combustion Research Facility, the University of Manchester, Bristol University, University of Southampton, and Hong Kong Polytechnic have successfully measured reaction rates of a second Criegee intermediate, CH3CHOO, and proven that the reactivity of the atmospheric chemical depends strongly on which way the molecule is twisted. The measurements will provide further insight into […]
