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...
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, $379,702 National Science Foundation project grant supports research to develop long tree-ring chronologies within and along the boundaries of the Great Plains region. The chronologies will aid in the reconstruction of past drought and moisture conditions as part of the Great Plains Drought Atlas. Researchers from the University of Wisconsin-Platteville, a regional primarily undergraduate institution, will work with students and partners in affected agricultural and tribal...
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 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 better interpret past climate and plan for future changes. The total funding amount is $324,677, with an award date of July 1, 2024 and an ultimate completion date of June 30, 2027. The key products and services to be delivered under this grant include: Using dendrometers (instruments that record tree growth in real-time) to...
The National Science Foundation awarded a $542,834 Project Grant to the University of Arizona under the Geosciences program (CFDA 47.050) to conduct collaborative research reconstructing Southern Rocky Mountains warm season temperatures over the past 2,000 years. The research aims to develop a temperature reconstruction using bristlecone pine from the Rio Grande headwaters region, augmented with updated hydroclimate reconstructions, to evaluate long-term regional temperature and hydroclimate...
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 Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences supports collaborative research to generate millennial-length reconstructions of sub-annual paleoclimate and extreme events in the Greater Yellowstone Ecoregion through tree-ring methodologies. Funded under the Geosciences program (CFDA 47.050), the $417,494 award to the University of Louisville runs from July 1, 2023 to June 30, 2026. Key products include developing millennial-length...
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,...
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...
