Scope: This document specifies the classification principles, classification methods, and coding rules for Earth system science data, as well as the classification and codes of Earth system science data. This document is applicable to the acquisition, processing, storage, processing, and sharing of Earth system science data, and other disciplines can also refer to and use it for reference. Main technical content: This standard specifies the classification principles, classification methods, and coding rules for Earth system science data, as well as the classification (first-level categories, second-level categories) and coding system for Earth system science data. The standard is applicable to the acquisition, processing, storage, processing, and sharing of Earth system science data, as well as to data platforms and system applications in related disciplines and fields. This standard uses element themes as the main classification dimensions for Earth system science data and adopts a two-level classification method of first-level categories and second-level categories. The first-level categories are mainly based on the Earth system science spherical structure and disciplinary characteristics, supplemented by land surface system data elements and attribute extensions, organized into 10 categories: atmosphere, land surface, human factors, biology, ocean, cryosphere, solid Earth, paleoenvironment, solar-terrestrial space physics and astronomy, and others. The second-level categories are classifications of element objects or their important attributes in the first-level categories, mainly referring to the classification scheme of the Global Change Master Catalog (GCMD), combined with existing national and industry standard classifications in various related disciplines, as well as the degree of data resource aggregation and user demand at home and abroad. Currently, there are 163 second-level categories designed. And through the normative appendix (Appendix A), the c
