Introduction

With the development of ocean observation technology, my country's observation methods have gradually developed from traditional coastal observation to buoy submersible observation and radar observation. A variety of observation methods such as survey, aerial observation and satellite remote sensing observation have been adopted, and an ocean three-dimensional observation network integrating star-air-earth has been preliminarily formed. for the sea To meet the needs of the development of ocean observation, standardize ocean observation activities, implement the "Regulations on the Administration of Ocean Observation and Forecasting" (Decree No. 615 of the State Council), Specification" (GB/T 14914-2006) was revised to "Ocean Observation Specification". "Ocean Observation Specification" includes general provisions, coastal observation, buoy submersible observation survey, shore-based radar observation, satellite remote sensing observation, data processing and quality control, among which the seashore code is the revised part, and the remaining 5 parts are new add part. GB/T 14914 "Ocean Observation Specification" is proposed to be composed of 6 parts. --- Part 1.General. The purpose is to stipulate the observation principle, observation content and quality control of ocean observation. --- Part 2.Coastal observations. The purpose is to stipulate the project time and technical requirements of coastal observation. --- Part 3.Buoy Submarine Observation. The purpose is to stipulate the observation items such as buoys, marine submersible buoys and surface drifting buoys, etc. skills requirement. --- Part 4.Shore-based radar observations. The purpose is to specify the observation items and timing, general regulations, and observation methods of shore-based radar observations. Laws and requirements, data processing and electromagnetic radiation protection. --- Part 5.Satellite remote sensing observations. The purpose is to specify sea surface temperature, marine meteorological elements, marine dynamic disasters, marine natural disasters Observation content and methods of hazards and sea surface height. --- Part 6.Data processing and quality control. The purpose is to specify the observation of seashore, buoy submersible, shore-based radar and satellite remote sensing. General requirements, processes, content and methods of data processing and quality control. GB/T 14914.6 focuses on refining the basic methods and requirements in the processing of operational ocean observation data, and regulates the collection of ocean observation data. Set, organize, process and quality control audit process, provide quality control processing methods that can be referenced, in order to clarify work ideas and improve work efficiency Finally, complete, accurate and reliable marine observation data and further data product production can be obtained. Ocean Observation Specification Part 6.Data processing and quality control
