This $409,233 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research by the University of Washington to develop a new 4D variational framework for assimilating multi-scale paleoclimate proxy data. The goal is to connect seasonal to millennial climate variability by integrating ocean and atmospheric data, using recent proxy data syntheses, borehole thermometry, and documentary records for validation. The project will produce a new global climate dataset bridging seasonal to centennial timescales, which could enable more robust interannual to decadal climate forecasting. Additional expected outcomes include support for graduate students, K-12 education tools, and public data resources for the paleoclimate and climate dynamics research communities.
