4Description document structure
The meteorological dataset description document is an electronic document consisting of a title and the description document content. Among them, the title is "Meteorological dataset description document"; the description document consists of "dataset information", "data source information", "dataset entity information", "referenced literature", "dataset production and technical support" and "others". For specific requirements, see Table A.1 of Appendix A. The description document content is organized in layers in the form of chapters and articles. Chapters are the first level, and the chapter numbers are written in Arabic numerals starting from 1. A clause is a subdivision of a chapter or clause. The clause number is in the form of Arabic numerals with a period, such as "\1.2" or "1.2.1". There should be a title after the chapter and clause number. The title should be aligned to the left, with one space between the title and the number. The title and the following content should be separated by lines, and no punctuation should be added at the end. The content under the chapter cannot be blank.
