中文摘要:针对原有省级CIMISS系统无法有效支撑现代化气象数据服务的问题,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,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。在测试对比中发现,本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5.2-22.3倍(倍数随着时间不断扩大),而格点数据则比原一体化平台提升了5倍多,充分验证了本方案的有效性。

Design of Provincial Meteorological Big Data Service System Based on CIMISS
Abstract:In view of the problem that the original provincial CIMISS system can not effectively support the modern meteorological data service. By using the distributed technology, Tianjin provincial meteorological big data service center is built, a unified data storage environment based on HBase, Gbase and distributed NAS is built, and a seamless connection with the provincial CIMISS system is formed, which meets the modern needs of Tianjin meteorological business. In the test and comparison, it is found that the query performance of this system is greatly improved: the automatic station data is 5.2-22.3 times higher than the cimiss system (the multiple increases with time), while the grid data is more than 5 times higher than the original integrated platform, which fully verifies the effectiveness of this scheme.
