About this award
The Trustees of Princeton University received a $765,282 grant award from NASA's Shared Services Center on June 1, 2022, to investigate the relationship between Southern Ocean salinity and global cloud feedback mechanisms. The research addresses a critical gap in climate science, as cloud feedback represents the greatest source of uncertainty in estimating climate sensitivity. Princeton's research team will conduct climate modeling experiments and analyze satellite-derived and in situ salinity data to understand how Southern Ocean salinity influences ocean heat uptake, global energy transport, and sea surface temperature patterns, ultimately affecting cloud feedbacks. The ultimate objective is to develop a satellite sea surface salinity-informed Bayesian estimate of global cloud feedbacks that will help reduce uncertainty in climate sensitivity projections.
The research is structured around five primary investigative questions examining the mechanisms through which Southern Ocean salinity modulates ocean heat uptake and influences global cloud patterns, the non-local effects of Southern Ocean heat uptake on cloud-controlling factors, the comparative effectiveness of salinity-driven heat uptake changes across ocean basins, and whether natural fluctuations in Southern Ocean salinity on decadal to centennial timescales result in state-dependent climate sensitivity. The contract, which rescinded a previous stop work notice, has an ultimate completion date of May 31, 2026, and carries no set-aside designation. This grant supports fundamental climate science research conducted at Princeton's Office of Research and Project Administration Division in Princeton, New Jersey.
