Project Grant 1702423

This three-year, $1,135,926 National Science Foundation project grant funds research to reconcile hydroclimate model projections and geologic data from a warmer period in the past to improve understanding of future water availability in the Southwestern United States. The awardee, Colorado State University, will collect new stable isotope data from sedimentary carbonates in New Mexico spanning the Middle Miocene Climate Optimum. Analysis of existing climate model simulations will differentiate...

This three-year, $511,918 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) funds research to develop a new framework for advancing climate model representations of cloud and convective processes. The grantee, Columbia University, will conduct fully-coupled, isotope-enabled climate simulations for the Last Glacial Maximum, Mid-Holocene, and Pre-Industrial periods using an ensemble of cloud and convective parameter sets. Paleoclimate data assimilation will...

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, $520,660 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research to constrain cloud and convective parameterizations in climate models using paleoclimate data assimilation. Specifically, the awardee, the University of Arizona, will conduct fully coupled, isotope-enabled climate simulations for the Last Glacial Maximum, Mid-Holocene, and pre-industrial periods using an ensemble of cloud and convective parameter sets. Paleoclimate...

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 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 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $526,171 to The Research Foundation for the State University of New York (RF-SUNY) to develop an isotope-enabled data assimilation system for studying the South American summer monsoon over the last millennium. The key objectives are to: 1) quantify the spatiotemporal characteristics of the South American summer monsoon and its relationship with the Atlantic Intertropical Convergence Zone...

This three-year $719,730 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research to constrain cloud and convective parameterizations in climate models using paleoclimate data assimilation. The awardee, William Paterson University of New Jersey, will conduct fully-coupled, isotope-enabled climate simulations for the Last Glacial Maximum, Mid-Holocene, and Pre-Industrial periods using an ensemble of cloud and convective parameter sets....

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 $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,...
