Abstract
High quality and well-managed climate data are the cornerstone of all climate services. Consistently assessing how well the data are managed is one way to establish or demonstrate the trustworthiness of the data. This paper presents the World Meteorological Organization’s (WMO) Stewardship Maturity Matrix for Climate Data (SMM-CD) and the subsidiary SMM-CD for National and Regional Purposes (SMM-CD_NRP). Both these matrices have been developed with the support of the WMO and its High-Quality Global Data Management Framework for Climate (HQ-GDMFC). These self-assessment tools enable data managers to discover WMO recommended data stewardship practices, determine a roadmap for future development and improvement, as well as compare their process against other data providers. Datasets which have been maturity assessed are included in the WMO Climate Data Catalogue, where users can include the results of these maturity assessments into their decision-making process. The SMM-CD contains four categories (data access, usability and usage, quality management, and data management) each of which has a number of aspects, with scores assigned to one of five levels. A smaller number of categories in the SMM-CD_NRP are assigned to four levels appropriate for operationally produced datasets which are national or regional in scope. We explore a number of case studies where these matrices have been applied, as well as supply links to where the Guidance Documents and Assessment Templates (which may be updated) can be found.

AND BACKGROUNDAll climate services, from data provision through seasonal climate forecasting, to the monitoring of, and adaptation to, climate variability and change, as well as disaster risk reduction depend on high quality and well-managed climate data
The CORE-CLIMAX System Maturity Matrix (SMM) measures the maturity of the systems that produce datasets of essential climate variables (ECVs) while DSMM measures the maturity of how digital datasets are being managed within the context of the open archival information systems (OAIS)
Summary
From data provision through seasonal climate forecasting, to the monitoring of, and adaptation to, climate variability and change, as well as disaster risk reduction depend on high quality and well-managed climate data. The HQ-GDMFC promotes establishment of, and compliance with, standards and recommended practices for sourcing, securing, managing, assessing, and cataloguing climate data, and for sharing infrastructure such as for data exchange, analysis and data service provision. Promoting acquisition of user feedback on the quality, fitness for purpose and usability of shared datasets The focus of this manuscript is the Stewardship Maturity Matrix for Climate Data (SMM-CD) and the subsidiary SMM-CD for National and Regional Purposes (SMM-CD_NRP). These matrices do not explicitly assess the scientific rigour involved in creating the dataset, e.g., how reliable the underpinning observations are, details of processing, homogenisation, scientifically-based adjustments etc What they do provide is information on the extent to which the dataset has clear documentation, support channels, is constructed with clear coding practices, applies quality control and assurance procedures, provides uncertainties, and adheres to data format and archiving standards. Links to the current SMM-CD and SMM-CD_NRP documents along with other supporting information are provided at the end of this manuscript
