Gathering users and developers to shape together the next-generation ocean reanalyses

It is the first time that reanalysis producers and users have gathered together to discuss the developments needed within the next generation of ocean reanalyses. Users’ long-term priorities (e.g. longer period, higher resolution, uncertainty quantification, and quality, specific formats to serve more communities of users) are clear as stated in the user survey and invited presentations. The review of current ocean reanalyses and plans indicates that producers are progressing in the right direction to fulfill users’ needs by increasing the horizontal resolution or extending the time series. However, to compensate for the high cost of computing power, multi-streams of ocean reanalyses are needed to meet users' preferences further. Several weaknesses of ocean reanalyses have been identified; biases and uncertainty in the ocean reanalyses should be estimated and reduced, with several specific examples provided in the previous sections. Finally, to improve ocean reanalyses, we need to work closely with different communities (atmospheric reanalyses, ocean modeling, data assimilation, and observations) to identify the best approach. The emerging needs (e.g., digital twins of the ocean) and new technologies (e.g., Artificial Intelligence) provide the ocean reanalysis community with challenges and opportunities for future development.
