Driving Ecosystem and Biogeochemical Models with Optimal State Estimates of the Ocean Circulation

Over several decades, atmosphere and ocean modelbased analyses have matured and proliferated, with climate modeling centers around the world generating routine real-time analyses as well as periodic retrospective reanalyses of the atmosphere and ocean state. These products support a range of scientific investigations, from initializing climate and Earth system model simulations, predictions, and projections to identifying and tracking the evolution of modes of variability, elucidating trends and extremes in the atmosphere and ocean, and providing a basis for decision support analyses, among a variety of other applications.
