Ocean reanalyses involve the combination of ocean observations with numerical models to yield an estimate of the three-dimensional, time-varying ocean circulation. Facilitated by progress in ocean modelling and data assimilation methods, increased supercomputing capacity and, most importantly, enhanced, routine and sustained in-situ and remotely-sensed ocean observations, the last 15 years saw the development and operational implementation of mesoscale eddy-resolving short-range ocean forecasting and reanalysis capabilities in an increasing number of oceanographic centres. Building and maintaining operational1 ocean forecasting systems requires as the Global Ocean Data Assimilation Experiment GODAE, its successor GODAE OceanView GOV coordinates multiagency efforts to coordinate the research, development and operational implementation of physical and biogeochemical ocean forecasting and reanalyses systems through its science team GOV continues the legacy of GODAE GOV Science Team, 2014 with its collaborators from more than 50 academic and national agencies worldwide with a research focus to improve short- to medium-range days to weeks operational ocean forecasting systems, and to enhance and sustain their development and routine operations.
