ALBUQUERQUE, N.M. — Hundreds of miles north of the Arctic Circle, Sandia National Laboratories researchers ensure the collection of important weather and climate data. By switching the gas used in their weather balloons, they have reduced their metaphorical footprint on the fragile Arctic ecosystem. More than three years ago, the Sandia-operated atmospheric measurement facility in […]

The destructive effects of supercooled liquid water on airplane safety and climate models
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 fly huge tethered balloons in […]
Hard cold work and unsung science heroes
Data for climate simulations doesn’t come easy ALBUQUERQUE, N.M. —The Sierra went down over the Arctic Ocean, about 60 miles from the northernmost tip of North America. One moment the unmanned aerial vehicle (UAV) with its 20-foot wingspan was up in the sky, gathering “hard” data over frozen terrain to help climate scientists in comfortable offices […]
