Session Description:
Earth science data quality and trustworthiness remain a big challenge with the growing diversity of datasets, the expanding needs of the scientific community, and scrutiny by public decision/policy-makers. Comprehensive, standardized, and accessible quality information, e.g. uncertainty, lineage and provenance, and complete and contemporaneous metadata/documentation is key for the trustworthiness of Earth science data. Researchers and public users need to efficiently find, access, and evaluate the quality level of Earth science data against their needs. Papers in this session cover topics on quality and trustworthiness of Earth science data, including: best practices for improving the capturing, describing, availability, and usage of Earth science data quality; assessment, characterization, and expression of data uncertainty, accuracy and precision; quality indicators for users to intuitively judge data quality; applications that manage and leverage quality information to improve user experience on data discovery and assist users to evaluate the fitness-for-use of Earth science data.
