The Argo data has become an important data source and basic support for the marine environment and climate change researches.Since the accomplishment of the Global Argo Real-time Ocean Observing Network in 2007,the annual quantity of data obtained from this network has increased steadily and the total amount of Argo data shows a massive growth trend.How to effectively manage,access and use Argo data in real-time has become a key issue in terms of data sharing.According to the spatio-temporal characteristics and the information service requirements of Argo data,this paper adopted the distributed hybrid database architecture to build a flexible and extendable cloud storage model,which was suitable for the global Argo data organization and management.Moreover,an efficient visualization method for the Argo gridded product based on Matlab was developed.Using the Flex RIA WebGIS service framework,we designed and realized a Global Argo Data Sharing and Service Platform.This platform consists of three main functions,including data query,data download and visualization,and now it has been deployed in the China Argo Real-time Data Center and has been providing services for data users.
