Poster presented at the #GHRSST23 science team meeting, 27 June-1 July 2022. Abstract As the size and complexity of the Earth observation data catalogue grows, the ways in which we interface with it must adapt to accommodate the needs of end users, both research-focussed and operational. Consequently, since 2020 EUMETSAT have introduced a suite of new data services to improve the ability of users to view, access and customise the Earth observation data catalogue they provide. These services, which are now operational, offer both GUI- and API- based services and allow fine grained control over how users interact both with products, and the collections they reside in. From early 2022, these services will also support the dissemination of the EUMETSAT Copernicus Marine Data Stream, including the Level-1 and Level-2 marine products from both the Sentinel-3 and Sentinel-6 missions at both near real-time and non-time-critical latency. Here, we give an overview of the capability of these data services, with examples of how to use them. In addition, we will outline the tools and resources that are available to assist users in incorporating these services into their workflows and applications. These include online user guides, python libraries and command line approaches to facilitate data access, and a suite of self-paced training resources and courses. This poster presentation will include demonstrations of the services, information on plans and schedules for the inclusion of future data streams, and the opportunity for new and experienced users to ask questions and give feedback.
