NOAA and Princeton team members
Pictured from left to right are V. “Ram” Ramaswamy, director of NOAA’s Geophysical Fluid Dynamics Laboratory; Sonya Legg, senior research oceanographer in atmospheric and oceanic sciences and CIMES associate director; Whit Anderson, deputy director of GFDL; Gabriel Vecchi, professor of geosciences and the Princeton Environmental Institute and CIMES Director; Jorge Sarmiento, Princeton’s George J. Magee Professor of Geoscience and Geological Engineering, Emeritus; and Craig McLean, assistant administrator for Oceanic and Atmospheric Research at NOAA.

In 2018 the Cooperative Institute for Modeling the Earth System (CIMES) succeeded the Cooperative Institute for Climate Science, which was founded in 2003 to foster research collaborations between Princeton University and the Geophysical Fluid Dynamics Laboratory (GFDL) of the National Oceanic and Atmospheric Administration (NOAA). The work of CIMES is carried out by the Atmospheric and Oceanic Sciences (AOS) Program, an independent program in the Department of Geosciences.

The Cooperative Institute for Modeling the Earth System (CIMES) is built upon the strengths of Princeton University in biogeochemistry, physical oceanography, paleoclimate, hydrology, ecosystem ecology, climate change mitigation technology, economics and policy; and those of GFDL in modeling the atmosphere, oceans, weather and climate. CIMES is an outgrowth of a highly successful fifty-year collaboration between Princeton University’s Atmospheric and Oceanic Sciences (AOS) Program and GFDL that has contributed to the development of oceanic and atmospheric models, performed research on climate and biogeochemical cycling and educated several generations of postdoctoral researchers and graduate students. CIMES and its predecessor CICS enhance and extend this long-term partnership by incorporating Princeton University faculty affiliated with the interdisciplinary Princeton Environmental Institute (PEI), thereby augmenting its expertise in the sciences, engineering and policy and facilitating new research collaborations.
