This $377,096 federal 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. The key objectives are to: 1) document drought and dust storm patterns in the Northern Great Plains during the 1930s Dust Bowl era, 2) measure the wind erosion potential of agricultural soils in the region using a portable wind tunnel, and 3) develop a modeling...
This $198,591 National Science Foundation project grant supports research on understanding the formation and impacts of warm-season trans-Atlantic African dust extremes. Funded under the Geosciences program (CFDA 47.050), the University of Kansas Center for Research will examine atmospheric circulation and land surface processes responsible for extreme dust events. Using satellite data, ground observations, and reanalysis, the researchers will identify causes of high dust loadings over the...
This Project Grant from the National Science Foundation's Division of Atmospheric and Geospace Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $480,039 to Texas Tech University from January 1, 2023 through December 31, 2025. The funding will support creation of the first national database cataloging dust events across the United States over the past 20 years, to advance understanding of their spatial and temporal distributions, meteorological causes, and impacts....
The National Science Foundation (NSF) Engineering program (CFDA 47.041) has awarded Utah State University (USU) a $498,424 five-year CAREER grant starting on July 1, 2024. The objective of this project is to advance the fundamental understanding of how plant ecosystems respond to exposure from salt-rich dust storms generated by the exposed dry lakebeds of inland saline lakes, such as the Great Salt Lake in Utah. The project will integrate laboratory and field methods with hyperspectral imaging...
This $800,565 Project Grant award from the National Science Foundation (NSF) Geosciences program (CFDA 47.050) supports research by the University of California San Diego (UCSD) Scripps Institution of Oceanography to explore the meteorological drivers of global mineral dust emissions. The project will leverage high-resolution climate model simulations to investigate the role of two key wind event types - downslope windstorms and haboobs - in generating atmospheric dust, and incorporate the...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) is providing $941,193 to the University of Utah to conduct research on cloud properties and their response to varying atmospheric and climate conditions. The key objectives are to further develop a theoretical model for predicting cloud size distributions, test the model's ability to account for cloud properties that are invariant to climate change, and derive minimal models to accurately predict...
The National Science Foundation Division of Atmospheric and Geospace Sciences awarded Arizona State University a $663,244 three-year Project Grant under the Geosciences program (CFDA 47.050) beginning July 1, 2022. This grant will fund collaborative research between Arizona State University and its partners to characterize dust entrainment processes through experimental and numerical studies of convective vortices like dust devils. The researchers will combine high-resolution modeling with...
This Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $360,000 to develop long tree-ring chronologies within and along the boundaries of the Great Plains region. The researchers, led by Columbia University, will use these tree-ring data to reconstruct past drought and moisture conditions over 500-1000 years, creating gridded reconstructions of spring/summer precipitation indices...
This three-year, $396,260 National Science Foundation project grant supports the development of tree-ring chronologies and climate reconstructions for the Great Plains region. Funded under the Geosciences program (CFDA 47.050), the researchers from the University of Arkansas will construct five gridded reconstructions spanning the Great Plains at 0.5 degree resolution, including the Standardized Precipitation Index for spring and summer seasons, precipitation totals for spring and summer, and...
The University of Utah was awarded a two-year, $153,579 Project Grant from the National Science Foundation Division of Earth Sciences under the Geosciences federal grant program (CFDA 47.050). The grant will support collaborative research examining laminated soil carbonate rinds as indicators of late Quaternary climate-vegetation relationships. As described under the CFDA, the Geosciences program strengthens fundamental understanding of Earth's integrated systems through basic research in...
