This $398,984 Project Grant award, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports research to quantify the biophysical, physiological, and phenological impacts of increasing carbon dioxide (CO2) levels on vegetation and their effects on future climate change. The research utilizes the Community Earth System Model to examine the direct impacts of CO2 fertilization and stomatal closure, as well as the indirect effects of a longer growing season, on...
This National Science Foundation Project Grant of $267,884 will fund research into critical zone hydroclimate variability and its impacts through May 2028. Under the Geosciences program (CFDA 47.050), the University of Texas at Austin will intensively measure root zone moisture storage across monitoring sites in Texas, California and Colorado. Measurements will extend below soils into weathered bedrock to evaluate responses to climate variability. Resulting datasets will inform ecohydrologic...
This $200,000 National Science Foundation project grant supports research at Wake Forest University from January 2023 through December 2024 to develop a modeling framework integrating vegetation phenology and dynamic water storage under drought conditions. Funded through the Geosciences program (CFDA 47.050), the research aims to better understand land-atmosphere interactions characterizing drought events in mountainous regions of Colorado. Specifically, the university will couple a land surface...
This $300,000 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to enhance the resilience of groundwater resources in major U.S. agricultural regions through a participatory planning approach. The project team at Southern Illinois University, with sub-awards to Iowa State University and the University of Nebraska, will develop an AI-based modeling system to empower farming communities in addressing groundwater depletion and...
This two-year, $180,000 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research into the influence of critical zone water storage on forest drought vulnerability and transpiration fluxes across complex mountainous terrain in Colorado. The grantee will employ field investigations using seismic surveys and electrical resistivity tomography to gather data on belowground structure and water storage along hillslope transects in the Boulder Creek...
The National Science Foundation (NSF) awarded a $290,728 Project Grant under the Geosciences (CFDA 47.050) program to the New Jersey Institute of Technology (NJIT) to conduct research on understanding how forests respond to drought and high temperatures. The key objectives of this 5-year project are to: Assess the impacts of hillslope hydrology on ecosystem function and plant physiological traits to predict tree mortality during climate extremes. Incorporate the research findings into Earth...
This $690,233 five-year Project Grant award was issued by the National Science Foundation's Geosciences Program (CFDA 47.050) to President and Fellows of Harvard College. The project aims to develop a basic scientific understanding of soil moisture and its changes under a warming climate, addressing two key questions: (1) what are the key controls on the spatial variability of soil moisture in the present-day climate, and (2) how will soil moisture change in a warming world? To address these...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $305,824 to Oregon State University (OSU) to conduct collaborative research on how changes in land cover and climate are impacting grassland water and carbon cycles below-ground. The project will: 1) quantify how woody encroachment alters soil water flow and storage, 2) measure the impact on groundwater and stream hydrology, 3) quantify changes in subsurface carbon processes, and 4)...
This $300,000 Project Grant award from the National Science Foundation (NSF) Integrative Activities program (CFDA 47.083) supports research to enhance water budget simulations across the continental United States by modeling vegetation's uptake of rock moisture. The primary objective is to implement an innovative approach within the Community Land Model Version 5 (CLM5) to represent this vegetation-rock moisture interaction and evaluate its impact on water budget predictions, especially during climate extremes.
The award enables the principal investigator to establish a mentorship relationship with a leading hydrologist to receive specialized training on advanced land modeling techniques at the National Center for Atmospheric Research. The research will truncate CLM5's root profile to stimulate vegetation growth into the weathered bedrock layer, allowing the model to account for the ability of plants to extract water stored in this layer. The performance of the original CLM5 and the rock moisture-enabled configuration will be compared to observational data on evapotranspiration and streamflow. This collaborative effort aims to advance the understanding of land-atmosphere interactions and improve the predictive capabilities of land models, ultimately contributing to more accurate assessments of water availability and environmental resilience across the continental United States.
