From Afghanistan to Alaska with atmosphere in between

November 5, 2019 • ALBUQUERQUE, N.M. — For Justin LaPierre, helping maintain an atmospheric research station at the northern tip of Alaska is “eerily reminiscent” of being deployed in the deserts of Afghanistan — just much colder. A U.S. Marine Corps veteran, LaPierre has worked as an observer at Oliktok Point for two years....

Hate to wait? Sandia looks to speed up climate research

October 17, 2019, Media Advisory • ALBUQUERQUE, N.M. — Presumably, Leonardo da Vinci could have saved a lot of time on his “Mona Lisa” if he had just slapped on two dots and a swoosh for a smiley face. But details take time. The same goes for running computer models and simulations. If you want oceans...

Exploring Arctic clues to secure future with new Sandia, university partnership

April 23, 2018 • ALBUQUERQUE, N.M. — The Arctic is undergoing rapid change, with sea ice melting and temperatures rising at a faster pace than anywhere else in the world. Its changing environment affects global security, politics, the economy and the climate. Understanding these changes is crucial for shaping and safeguarding U.S. security in...

Effects of climate change on communally managed water systems softened by shared effort

April 16, 2018 • ALBUQUERQUE, N.M. — Shared fates and experiences in a community can help it withstand changes to water availability due to climate change, a recent study by Sandia National Laboratories researchers found. “During our research, a community’s ability to withstand natural and social pressures was routinely pinpointed to the fact that...

Biologically inspired membrane purges coal-fired smoke of greenhouse gases

April 11, 2018 • ALBUQUERQUE, N.M. — A biologically inspired membrane intended to cleanse carbon dioxide almost completely from the smoke of coal-fired power plants has been developed by scientists at Sandia National Laboratories and the University of New Mexico.[caption id="" align="align…

The destructive effects of supercooled liquid water on airplane safety and climate models

November 3, 2016 • ALBUQUERQUE, N.M. — Supercooled  water sounds smooth enough to be served at espresso bars, but instead it hangs out in Earth’s atmosphere, unpredictably freezing on airplane wings and hampering the simulations of climate theorists. To learn more about this unusual state of matter, Sandia National Laboratories atmospheric scientist Darielle Dexheimer and colleagues have organized an expedition to...
Ice pops from a balloon's tether line as Sandia National Laboratories researcher Darielle Dexheimer gathers in an instrumented balloon at the Atmospheric Radiation Measurement research station at Oliktok Point, Alaska. The balloon is about 25 feet above Dexheimer's head and the lines are completely iced over.

City resilience: Sandia analyzes effects of rising sea levels in Norfolk

March 28, 2016, Media Advisory • ALBUQUERQUE, N.M. — In Norfolk, Virginia, an East Coast city that’s home to the world’s largest naval station and important seaports, catastrophic flooding could damage more than homes and roads. A new study from Sandia National Laboratories assesses how much the city, its region and the nation would suffer in...
