中文摘要:随着气象业务的不断发展,原有省级CIMISS系统已经无法有效支撑现代化的气象数据服务需求。本文利用分布式技术,构建了天津省级气象大数据服务中心,搭建了以HBase、GBase、分布式NAS为基础的统一数据存储环境,并透过MUSIC全国统一气象服务接口与省级CIMISS系统形成了无缝对接,满足了天津气象业务的现代化需求。同时,针对需求,提供了多种数据服务方式,并透过灵活的数据订单方式满足了不同的个性化需要。而在测试对比中发现,本文系统的查询性能得到较大提升:自动站数据比CIMISS系统提升了8倍左右,而格点数据则比原一体化平台提升了5倍多。

Design of provincial meteorological big data service system based on cimiss
Abstract:With the continuous development of meteorological services, the original provincial cimiss system has been unable to effectively support the needs of modern meteorological data services. In this paper, the distributed technology is used to build Tianjin Provincial Meteorological big data service center, build a unified data storage environment based on HBase, gbase and distributed NAS, and form a seamless connection with the provincial cimiss system through the music national unified meteorological service interface, which meets the modern needs of Tianjin Meteorological business. At the same time, it provides a variety of data service methods, and satisfies different personalized needs through flexible data order methods. In the test and comparison, it is found that the query performance of this system is greatly improved: the automatic station data is about 8 times higher than the cimiss system, and the grid point data is more than 5 times higher than the original integrated platform.
