Project Grant 1805490

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 $198,435 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project titled "P4CLIMATE--A Paleo Perspective on the Links Between Climate and Food Security." The project will quantitatively assess shifts in maize production in North America over the past 1,200 years by merging paleoclimate, weather generation, and crop modeling data. This research aims to understand the impacts of prolonged droughts,...

The University of Arizona, as the prime recipient of Cooperative Agreement G24AC00080 from the U.S. Geological Survey's National and Regional Climate Adaptation Science Centers (CFDA 15.820) program, will execute a $349,400 research project titled "Atmospheric Rivers and Downslope Winds as Tollgates of Aridification in the Southwest: Impacts on Water Resources and Wildfire Management." The project aims to assess the long-term impacts of climate change on precipitation patterns,...

This National Science Foundation Project Grant of $800,670 will support research to extend tree-ring based reconstructions of Atlantic Gulf Basin hydroclimate over the Common Era. Led by the University of Arizona with completion expected by June 2025, the project aims to collect old-growth bald cypress and longleaf pine samples from trees harvested in the late 19th and early 20th centuries. These extended tree-ring chronologies will be used to develop regional and seasonal hydroclimate...

This Project Grant from the National Science Foundation's Integrative Activities program (CFDA 47.083) provides $220,480 to the University of Iowa to quantify the impacts of anthropogenic climate change on drought effects from 2022-2024. The University will analyze how much past climate change has exacerbated drought impacts on plant productivity during the 2012-2015 California drought and 2012 Midwest drought. Using remote sensing and climate modeling, the researchers will attribute changes...

Grant Award Summary The University of Arizona received a $303,942 Project Grant from the National Science Foundation's Division of Atmospheric and Geospace Sciences (Geosciences Program, CFDA 47.050) effective September 1, 2025, through August 31, 2028. This collaborative research initiative will extend tree-ring reconstructions of drought in the Colorado River Basin back 2,000 years to characterize drought severity and duration patterns, with particular focus on investigating a potentially...

This National Science Foundation award under the Geosciences program (CFDA 47.050) provides $381,192 to the University of Missouri System from July 1, 2022 to June 30, 2025. The funding will support development of tree ring chronologies from juniper, pine, and taxodium trees within and near the Great Plains to reconstruct past seasonal precipitation, soil moisture balance, and drought over the region from the Medieval period to present. Researchers will produce five gridded reconstructions at...

This $211,743 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to reduce uncertainties in tree-ring records of wet extremes to aid interpretations of past climate and plan for future changes. The primary objectives are to: Use dendrometers to measure how tree growth responds to changes in precipitation frequency, intensity, and timing at sites in the AmeriFlux network. Reconstruct wet extremes of precipitation from previously collected tree-ring...

This $270,754 Project Grant award from the National Science Foundation's (NSF) Biological Sciences program supports collaborative research to investigate the impacts of the ongoing megadrought in the American West on soil moisture, ecosystem carbon-water cycling, and remote sensing capabilities. The research team, led by the Trustees of Indiana University, will synthesize hundreds of long-term soil moisture measurements with remotely-sensed data and eddy covariance tower observations to...

This National Science Foundation (NSF) award under the Geosciences program (CFDA 47.050) is funding a $216,562 collaborative research project between the University of Southern California (USC) and George Mason University to characterize hydroclimate changes over Western North America and Europe in response to the global warmth of the Middle Miocene period (around 15 million years ago). The project aims to understand how water availability may change in a warming climate by investigating...
