In order to participate in the international exchange of Bailong buoy data with the standard format, the data transmission process is designed, including the data measurement, satellite transmission, station receiving, real-time data quality control, storage in cloud, and data link for uploading to China Meteorological Administration (CMA) via FTP. According to the standard binary universal form of the representation of meteorological data (BUFR) recommended by World Meteorological Organization (WMO), CMA converts the original format into BUFR and packs them according to the rules of Global Telecommunication System (GTS). At present, the meteorological and ocean observation data of Bailong buoy is distributed and shared to GTS in real time. Global users can get the Bailong buoy data from GTS, and identify and decode the data by the header identification. The Bailong buoy becomes the first Chinese mooring buoy shared with other countries by GTS, which indicates that the data providing capacity of China's climate mooring buoy has achieved the world's advanced level.
