- 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 $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...

- The National Science Foundation's Division of Earth Sciences awarded a $464,646 Project Grant to the University of Wyoming beginning August 15, 2025 and extending through July 31, 2028, under the Geosciences program (CFDA 47.050). This collaborative research initiative will produce geological evidence and scientific analysis quantifying past changes in precipitation, evaporation, and snowmelt patterns in the Rocky Mountains over the 15,000 years since the last ice age. The project will...
- Northern Arizona University will receive $390,528 under a three-year Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) to reconstruct temperature and hydroclimate trends in the Southern Rocky Mountains over the past 2,000 years. The university will develop new temperature reconstructions using bristlecone pine samples from the Rio Grande Headwaters region, augmented with updated hydroclimate reconstructions. Researchers will address how temperature influences...
- This $202,000 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to analyze precipitation variability and extreme rainfall events in Southern California. The project will combine tree-ring data, historical weather observations, and climate model simulations to reconstruct the range of precipitation variability over time in this region, with a focus on atmospheric rivers and extreme precipitation. The research goals include quantifying the...
The National Science Foundation Division of Earth Sciences awarded the University of Arizona $328,683 on August 1, 2026, under the Geosciences program (CFDA 47.050) to reconstruct 3,000 years of hydroclimatic variability in the western United States using giant sequoia tree-ring chronologies. The project will update and expand a network of giant sequoia tree-ring chronologies across the Southern Sierra Nevada that has not been comprehensively updated since 1995. Researchers will combine tree-ring data with state-of-the-art hydrologic models to reconstruct snow water equivalent, soil moisture, precipitation, drought, and watershed-scale hydroclimate over the multimillennial timescale. The work will develop new paleo-hydroclimatological methods to characterize spatial and temporal variability of hydroclimate at watershed scales, providing tools for investigating natural variability in snowpack, soil moisture, precipitation, and drought. By placing recent drought and climate whiplash events into a 3,000-year context, the project will improve understanding of the frequency, magnitude, and persistence of hydroclimatic extremes projected to become more frequent in coming decades. The project includes STEM workforce training and outreach to practitioners and the public. Work is performed in Tucson, Arizona. The award period runs through July 31, 2029.
