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...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $202,000 to analyze precipitation variability and extreme rainfall events in Southern California through model simulation and tree-ring reconstruction. The project aims to combine historical weather observations, climate model simulations, and new tree-ring data to understand the range of precipitation variability and the mechanisms driving extreme rainfall associated with atmospheric...
This $276,385 Project Grant award from the National Science Foundation's (NSF) Geosciences program (CFDA 47.050) supports collaborative research to reconstruct a 250-300 year record of rainfall extremes and Amazon River water levels in the Eastern Amazon region. The key objectives are to: Use tree-ring data from Cedrela odorata and historical records to create a long-term hydroclimate reconstruction for the region. Constrain the elevations of high and low Amazon River levels in the 19th century....
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 award, funded by the National Science Foundation (NSF) Biological Sciences program (CFDA 47.074), aims to improve understanding of how forest structure and function influence "ecological climate" - the climate experienced by organisms within forest canopies. The $424,492 project, running from August 2024 to July 2028, will integrate data from the National Ecological Observatory Network (NEON) into advanced forest canopy models to evaluate how forest diversity...
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 $329,272 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund research to investigate the impacts of sea level rise on stemflow dynamics and associated hydrological and biogeochemical processes in coastal forests along the Atlantic seaboard. The University of Delaware, as the prime awardee, will use field measurements, laboratory analyses, and statistical modeling to understand how changes in stemflow (precipitation channeled down tree...
The National Science Foundation (NSF) awarded a $562,254 Project Grant under the Geosciences program (CFDA 47.050) to The Trustees of Columbia University in the City of New York. The purpose of this 3-year grant, with an award date of February 1, 2024, is to use stable oxygen isotopes measured in tree-ring cellulose across the tropical Americas to reconstruct wet season precipitation variability over the past 200 years. This research aims to gain insights into large-scale tropical climate...
This $103,171 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a collaborative research effort to advance the understanding of global paleoclimate through the expansion of African dendrochronology. The project aims to measure radiocarbon, tree ring width, and wood anatomy from dominant tree species in Zambia to develop multi-century climate records. These data will be used to create a gridded precipitation reconstruction for the region and...
This $670,495 National Science Foundation project grant will fund research into drought and cold resistance in Northeastern U.S. tree species. Under the Biological Sciences program (CFDA 47.074), the University of New Hampshire will lead a collaborative effort to investigate how Northeastern tree species respond to drought and how those adaptations impact vulnerability to other climate stressors like extreme cold. The research team will conduct extensive field measurements of drought-related...

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:

  1. Use dendrometers to measure how tree growth responds to changes in precipitation frequency, intensity, and timing at sites in the AmeriFlux network.
  2. Reconstruct wet extremes of precipitation from previously collected tree-ring width data in the International Tree-Ring Database across various climate zones in the U.S.
  3. Evaluate uncertainties in tree-ring hydroclimate reconstructions and estimate the impact of future hydroclimate extremes on forest health using forward proxy modeling.

The award also includes training for a postdoctoral researcher, graduate student, and undergraduate students, as well as climate change communication through public outreach events in partnership with a nonprofit cinema. The project will be conducted by the University of North Carolina at Chapel Hill from July 1, 2024 through June 30, 2027.
