This standard specifies the two-level classification and coding of meteorological data, and is the basic standard for further classification of meteorological data. This standard specifies the classification method, two-level classification and coding of meteorological data. This standard applies to the management of meteorological data during the collection, processing, storage, archiving and service of meteorological data.
Meteorological data is earth science data with both time and space attributes, and is also one of the oldest, most well-preserved and most systematic earth information resources since the written records in China. For a long time, China has accumulated a large amount of basic meteorological data or data, and new observation data is still increasing year by year. Due to the complex sources, various types, various formats, different forms of expression and huge amount of data of meteorological data, the complexity and difficulty of meteorological data management are increasing day by day. With the development of information technology, more and more meteorological data are stored and managed in digital form. In order to adapt to the standardized management of digital meteorological data, the classification and coding of meteorological data must be standardized.
In the absence of a unified meteorological data classification standard at home and abroad, the preparation of this standard refers to the binary universal data representation format (FM 94 BUFR) formulated by the World Climate Program (WCP) of the World Meteorological Organization, the Climate Data Detection and Management Program (WCDMP) and the World Weather Watch Network (WWW) Basic System Commission (CBS) of the World Meteorological Organization in 1989, as well as relevant information classification and coding standards in China.
This standard specifies the two-level classification and coding of meteorological data, which is the basic standard for further refinement of meteorological data classification.

Due to the complex sources, various types, various formats, different forms of expression and huge amount of data of meteorological data, the complexity and difficulty of meteorological data management are increasing day by day.

Surface classification method
Select several attributes (or features) of the classification object, and divide the classification object into a group of independent categories according to each attribute (or feature). Each group of categories constitutes a "surface". Then arrange each "surface" in parallel in a certain order. When using it, the corresponding categories in the relevant "surface" are combined according to the specified arrangement order of the "surface" as needed to form a new composite category. 3.5

4 Methods for classification and coding of meteorological data
4.1 Classification method
According to GB7027, a mixed classification method is adopted. Meteorological data are divided into fourteen categories (primary classification) according to their content attributes and source attributes. Each major category of meteorological data is classified according to its data characteristics by selecting different combinations (surface classification) of content attributes, regional attributes, time attributes, spatial attributes, source attributes, observation attributes, format attributes, etc. (secondary classification).
4.2 Coding method
The classification code consists of the major category code and the attribute codes of the secondary classification. The codes are separated by underscores. The major categories and attribute codes of meteorological data are represented in two ways: one is a simple code (Arabic numeral code) and the other is an identifier (composed of English letters and Arabic numerals, usually the first digit should be an English letter). The major category simple code is represented by one English capital letter, and its identifier is composed of four English capital letters. The attribute simple code of the secondary classification is represented by three Arabic numerals, of which 900 to 998 are extension codes, which are used for temporary extension of attribute content in individual special cases. The specific meaning of the extension code should be explained in the corresponding description file of the meteorological data; the identifier is composed of a string of English capital letters or English capital letters with English capital letters as the first digit and Arabic numerals. The identifier can reflect the basic meaning of the major category and attribute, and should be easy to identify manually and conform to the English abbreviation convention. 4.3 Extension of meteorological data classification coding
This standard specifies the coding of the primary and secondary classifications of meteorological data. The further classification of various meteorological data, that is, the classification codes below the second level (excluding the second level), can be separately stipulated on the basis of this standard. The classification below the second level generally adopts the linear classification method, and the principles for formulating the classification codes should be consistent with this standard. 5 Meteorological Data Classification and Codes
