The XDS is powered by ECMWF Data Store Service (ECMWF-DSS) technology (access via CDS-API, discovery forms etc). It shares the same authentication system, so that users can access any dataset across all data stores (CDS, ADS, EWDS, ECDS).
Find all information how to access a dataset in XDS and the available tools and tutorials in the XDS home page https://xds.ecmwf.int
