Meteorological Data Files Quick Download Service System

The development of meteorological data service system is summarized as 4 stages: Stand alone file retrieval stage, the interface calling stage, database system stage and distributed data service stage. The current service system can meet the needs of most users querying data, but for meteorological professional and operational users, the system has certain limitations. These users call for a new data service system that offers fast bulk download meteorological data services, which should also be established to make up for the deficiencies of existing meteorological data sharing service system. According to operational requirements, a new meteorological data service system is designed based on metadata technology, through which professional and operational users can quickly download batch of real time meteorological data. The system is based on front end application systems and background management systems to achieve a bulk download, file directory navigation, data synchronization update, multi threaded HTTP, security management, and flexible configuration capabilities. With the system, users can use third party software to download great amounts of meteorological data files. Based on the file directory navigation provided by the system, users can access the data level by level following the data classification and the time characteristics, and can flexibly select and retrieve the data. The system achieves the meteorological data collection system synchronous update, and users can access to download the latest meteorological data products. The system is a brand new design for the meteorological data services, and has been well accepted by the professional users. It has a wide range of promotional value and is good reference for future development of meteorological data service system.
