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 hydrology model with a prognostic phenology model to capture feedbacks between dynamic water storage, vegetation growth, water use, and phenological changes in response to environmental conditions. Satellite observations of plant greenness and density will be assimilated using data assimilation techniques to reduce uncertainty in forecasts of plant states and propagation of uncertainty through estimates of dynamic water storage and land surface water, energy, and carbon fluxes. The modeling framework will be validated using data from forested mountain basins in Colorado studied by the Dynamic Water Cluster of the Critical Zone Network to improve predictability of drought impacts.
