The task team (TT) on the EVOLUTION OF THE REGIONAL/GLOBAL TASK SHARING (short R/G TS TT) has produced this report ���GHRSST R/G TS System Architecture (GSA)��� which describes the agreed new framework for the GHRSST R/G TS. The report describes the data management and distribution services and specifies the services that are required to implement it. The new R/G TS was reviewed and approved at GHRSST annual meeting in 2020. Information on Data Assembly Centres (DAC) service provision was gathered in a survey conducted for GHRSST XXI meeting in 2020. The original system set up to distribute GHRSST data products has grown and become more complex with the addition of more Data Assembly Centres (DACs) and data producers. The GHRSST Data and Services Technical Advisory Group (DAS-TAG) recognised that a well-defined system with greater decentralisation of data ingestion and distribution would better prepare GHRSST for future growth and facilitate the participation of new data producers. The R/G TS TT was tasked with the definition, design and oversight of implementation of the new Regional and Global Task Sharing System. The new R/G TS will provide a central end-point access (dataset catalogue and federated OpenSearch granule-level search service) to otherwise distributed data archiving, distribution and search services (implemented by DACs).
