The National Science Foundation (NSF) awarded a $298,441 Project Grant under the Geosciences program (CFDA 47.050) to the University of Oklahoma, operating through its Office of Research Administration, for a collaborative research project on using polarimetric radar observations, cloud modeling, and in situ aircraft measurements to improve large hail detection and warnings. The project aims to better understand the microphysical processes of hail generation and develop more advanced...
This federal Project Grant award from the National Science Foundation's (NSF) Division of Polar Programs (CFDA 47.078 - Polar Programs) in the amount of $231,050 provides funding for a postdoctoral fellowship to study the impacts of snowfall and storm events on the coupled Antarctic sea ice and ocean system. The primary goal of this research is to characterize the evolution of the Antarctic sea ice mass budget and upper ocean properties following perturbations from snowfall and storms. The...
This $377,096 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to assess current and future dust flux from the Northern Great Plains of the United States under extreme climate variability. The research team, led by the University of South Dakota, will collect historical weather and drought data, conduct wind erosion measurements on agricultural soils, and develop models to predict dust emissions in the Northern Great...
The National Science Foundation Division of Polar Programs awarded The Ohio State University a $844,359 Project Grant under the Polar Programs (CFDA 47.078) federal grant program. The grant supports applying observations from the Year of Polar Prediction - Southern Hemisphere targeted observing periods to advance winter numerical weather forecasting for the U.S. Antarctic Program.

This Project Grant award from the National Science Foundation's (NSF) Geosciences program (CFDA 47.050) will provide $652,433 to Iowa State University of Science and Technology to conduct research on mesoscale convective systems (MCSs) and associated high-wind phenomena like bow echoes and derechos. The key objectives are to: 1) examine processes contributing to upscale growth and bow echo formation in MCSs, 2) improve understanding of factors leading to long-lasting, significantly severe...
This National Science Foundation (NSF) Geosciences program Project Grant award of $381,865 to Colorado State University aims to understand how the predictability of severe weather events, such as tornadoes, hail, and flooding, may change as the climate warms. The research will generate and analyze large datasets of numerical weather model forecasts to assess how the ability to predict severe storms evolves in recent (20th century) versus future (21st century) climate scenarios. This work could...
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,...
