- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded $399,572 to the University of Colorado on January 1, 2026, for continued U.S. researcher access to the CLOUD (Cosmics Leaving Outdoor Droplets) consortium chamber at CERN to study atmospheric new-particle formation and growth. The award funds three years of experiments using CLOUD's 26 cubic meter stainless-steel chamber—a facility with no U.S. equivalent—to develop molecular descriptions of particle nucleation...
- The National Science Foundation awarded San Jose State University Research Foundation $374,521 on July 1, 2026, under the Geosciences program (CFDA 47.050, AGS-FIRP Track 2) to conduct cloud chamber experiments investigating aerosol-mixed phase cloud interactions. The project will generate multiple steady-state mixed-phase clouds using varying concentrations of cloud condensation nuclei and ice nucleating particles across different temperature gradients in Michigan Tech University's PI Cloud...
- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded Utah State University $424,932 on July 1, 2026, under the Geosciences program (CFDA 47.050) to investigate mesosphere and lower thermosphere neutral temperature and wind responses to geomagnetic storms equatorward of the auroral zone. The project conducts comprehensive numerical investigations of intense geomagnetic storms using advanced atmospheric models combined with resonance lidar temperature and wind...
- The National Science Foundation awarded a $747,029 Project Grant to the University of Utah under the Geosciences federal grant program (CFDA 47.050) to conduct an observational evaluation of the effects of atmospheric temperature and turbulence on hydrometeor fall speeds. Over a three-year period ending May 2025, the University will deploy instrumentation at a high-elevation field site in Utah's Wasatch Mountains to directly and automatically measure individual snowflake motions, air turbulence,...
- This $307,540 federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund research to investigate the role of Arctic clouds in modifying surface temperature and energy absorption. The research aims to clarify how different cloud regimes develop and their impacts on Arctic warming and sea ice extent. The project will combine observations from an Alaska field site with high-resolution regional climate models to characterize cloud formation processes...
- This National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences Project Grant award, with a total funding amount of $532,712, supports collaborative research to investigate the physical processes underlying transitions in marine stratocumulus cloud cover over the eastern North Atlantic region. The research aims to develop a causal framework to better understand the complex interactions that drive changes in cloud structure, from continuous stratocumulus layers to more broken...
The National Science Foundation Division of Atmospheric and Geospace Sciences awarded the University of Utah $240,286 on September 1, 2026, for collaborative research on cloud transitions during marine cold-air outbreaks through the Geosciences program (CFDA 47.050). The research uses airborne observations and numerical modeling to investigate how precipitation, sublimation, and surface fluxes drive the transition of organized cloud rows to deeper, open-cell clouds as frigid Arctic air moves over warmer open waters. The project combines data from the Cold-Air Outbreak Experiment in the Sub-Arctic Region (CAESAR) field campaign—including radar, lidar, cloud probe, and isotopic measurements—with large eddy simulation modeling and radar simulation to test hypotheses about environmental thermodynamics, the role of precipitation in generating cold pools that organize convection, sublimation dynamics, and the maintenance of open-cell cloud structures. Results are intended to improve marine weather forecasting and numerical weather model development, with graduate student training embedded in the research. Performance of work occurs in Salt Lake City, Utah, with a period of performance ending August 31, 2028.
