FENGYUN-3 SERIES METEOROLOGICAL SATELLITE DATA ARCHIVING AND SERVICE SYSTEM

This paper introduces the characteristics and the new technologies applied in Fengyun-3 Series Meteorological Satellite Data Archiving and Service System. The system integrates several high-performance servers, high availability disk array, large-scale automated tape library as well as operation system, database, storage software and application software, all of which constitutes archive and service application clusters. The application of configured dynamic load container technology and multi-server processing load balancing and parallel computing technology makes the cluster a highly scalable, available, efficient operational system to realize all levels of satellite data archiving, customization, retrieval, dynamic information release, operation monitoring, management, and other functions. Internet-based full dataset sharing, distributed file system, spatiotemporal integration of database storage, WebGIS global satellite image distribution, visual processing and display technology are adopted in the system to improve data sharing and service. Completion of the system meets the needs of operational meteorological satellite, achieving daily 4 TB data storing and daily 1 TB data download service. The system running in NSMC/CMA is the first one to provide internet-based full archive dataset (online, nearline and offline) sharing service in the area of Chinese civil remote sensing satellite data services.
