Fengyun-4A Meteorological Satellite Data Service System

Abstract

This paper introduces the characteristics and the new technologies applied in Fengyun-4A(FY-4A) Data Service System. The system is an important part of Fengyun-4(FY-4) series satellite ground application system, and also is the new generation platform for meteorological satellite data sharing services. 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 system adopts cloud-computing technology, big data technology, WEBGIS technology to establish a stable, reliable and secure operational satellite data archive platform, which not only provides data retrieval and download services, but also provides various auxiliary means and information assistance.
