Sandia cloud-resolving climate model meets world’s fastest supercomputer
April 7, 2023 • ALBUQUERQUE, N.M. — Focused on the accuracy of climate predictions, a computational team led by Sandia National Laboratories recently achieved a major milestone with a cloud-resolving model they ran on Frontier, the world’s first exascale supercomputer. “We have created the first global cloud-resolving model to simulate a world’s year of...

Balloons and drones and clouds; oh, my!
August 14, 2017 • ALBUQUERQUE, N.M. — Last week, researchers at Sandia National Laboratories flew a tethered balloon and an unmanned aerial system, colloquially known as a drone, together for the first time to get Arctic atmospheric temperatures with better location control than ever before. In addition to providing more precise data for weather...

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.

Alaskan North Slope climate: hard data from a hard place
August 13, 2012 • Researchers examine clouds (from both sides now) and the structure of the atmosphere BARROW, Alaska — Sandia National Laboratories’ researcher Mark Ivey and I (science writer Neal Singer)  are standing on the tundra at an outpost of science at the northernmost point of the North American continent. We are five miles northeast...
