Listed Global datasets were assessed using the WMO Stewardship Maturity Matrix for Climate Data (SMM-CD) which contains four categories (data access, usability and usage, quality management, and data management) each of which has several aspects, with scores assigned to one of five levels. Individual datasets information and link to the Climate Explorer for metadata and visualization are provided for most of the individual datasets. Individual assessments are available upon request at climate-data@wmo.int. The SMM-CD Guidance Booklet can be downloaded on figshare (Note Booklet holds link to SMM-CD Template).
