There is a need to develop innovative methodologies that integrate satellite data, in situ measurements, and numerical models to enhance the accuracy of upper-layer ocean circulation products across diverse ocean circulation regimes. Current approaches lack the synergetic optimisation needed to address these priorities effectively across different ocean environments.
Earth Observation (EO) can significantly enhance ocean monitoring by providing high-resolution satellite data that, when combined with in situ measurements and numerical models, improves the accuracy of upper-layer ocean circulation products. EO enables continuous, global-scale observation of diverse ocean regimes, including polar seas, coastal areas, and upwelling regions. This improved ocean data supports key applications such as pollution tracking, safe navigation, sustainable fisheries management, and the development of renewable marine energies. EO's ability to provide real-time and historical data also supports more informed decision-making for ocean sustainability, aligning with the United Nations Decade of Ocean Science for Sustainable Development.
