The tabledriven code forms are the data format recommended by the World Meteorological Organization and widely used around the world. It is also one of the major international common formats used in the standardization of meteorological data format within the China Meteorological Administration. Based on the main architecture of the observation system and CIMISS data environment, the representative observation data and products are selected, and the pilot operating system of Table Driven Code Forms is established. According to the selfdescription and flexible expansibility characteristics of table driven code forms, the coding templates are developed, and the code tables are dynamically loaded by the encoding/decoding software. The mapping and conversion of coding elements and sequences to the storage elements and models are realized, and the database storage model is designed. The complete data flow of encoding, transmission, processing, storage, and application is tested and verified, and can be the reference for the implementation of data format standardization based on tabledriven code forms.
