This $1,572,670 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a field campaign in the mountains of Colorado to study cloud and precipitation processes that influence orographic snowfall. The campaign, titled "Snow Sensitivity to Clouds in a Mountain Environment" (S2NOCLIME), will deploy advanced remote sensing and ground-based instruments to collect comprehensive data over the 2024-2025 winter season. The research aims to address...
This $1.5 million National Science Foundation project grant supports research into secondary marine aerosol precursors and their links to aerosol growth during Arctic sea ice melt onset. Funded under the Geosciences program (CFDA 47.050), the goal is to advance understanding of secondary marine aerosol formation in the atmosphere and its impact on cloud properties and climate. Colorado State University will conduct measurements of volatile organic compounds and reduced sulfur compounds aboard...
This $128,741 Project Grant award from the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) supports the participation of U.S. scientists in the international HALO-South field campaign to measure clouds and aerosols over the Southern Ocean. The project will provide flight planning and immediate post-campaign data analysis to better understand aerosol sources and sinks and improve climate models' representation of Southern Ocean clouds. Key activities include forecasting...
This $368,518 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a field campaign focused on studying cloud and precipitation processes in a mountainous environment. The "Snow Sensitivity to Clouds in a Mountain Environment" (S2NOCLIME) project will deploy advanced remote sensing and ground-based instruments in the Park Range of northern Colorado to collect comprehensive data over the 2024-2025 winter season. The research aims to...
This $467,067 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research at Texas A&M University to increase fundamental understanding of the physical mechanisms that drive heterogeneous ice nucleation in the atmosphere, with a particular focus on contact nucleation. The research aims to address key science questions around establishing reliable methods for measuring contact ice nucleation, understanding the importance...
This $199,242 Project Grant award, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a comprehensive research initiative at Colorado State University focused on enhancing scientific understanding of snowflakes and snowfall.

This $551,788 Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports research by Texas A&M University to study the impacts of aerosols on cloud microphysics, charge structures, and precipitation patterns related to sea breeze convection and thunderstorms along the Texas Gulf Coast region. The key objectives are to: (1) analyze observational data on aerosol, cloud, precipitation, and lightning characteristics; (2) assess the impacts of...
The National Science Foundation Division of Polar Programs awarded Colorado State University a $673,107 Project Grant under the Polar Programs (CFDA 47.078) federal grant program. The grant will support improved understanding of aerosol-cloud interactions during the Arctic sea ice melt period from May to June 2023. As part of the Swedish-led ARTOFMELT expedition aboard the icebreaker Oden in the Arctic Ocean, the university will conduct observations and modeling to characterize aerosol...
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...
