【摘要】：中国气象局S2S(Sub-seasonal to Seasonal)数据归档中心建设是中国气象局承担世界气象组织(WMO)的世界天气研究计划(WWRP)和世界气候研究计划(WCRP)任务,由国家气象信息中心负责设计和实现。该文介绍了S2S数据归档中心建设中涉及的数据交换、数据检查及处理、数据归档存储及数据服务门户全流程系统设计和实现。针对各业务中心生产的S2S数据配置差异较大造成数据交换、同步较难这一问题,采用基于FTP(file transfer protocol)的数据推送和基于ECMWF(European Center for Medium-range Weather Forecasts)WebAPI主动数据下载相结合的方式,说明数据交换、同步方法和策略。由于S2S数据量巨大难以高效管理服务,已设计统一的数据组织形式和存储规则,实现根据数据检索条件解析获取数据存储位置,提供便捷的数据检索下载服务。自2015年11月15日中国气象局S2S数据门户系统对外开放,目前数据门户系统已有超过18个国家的300个用户注册并下载数据。
[Abstract]:The construction of S2S (Sub-seasonal to Seasonal) data Archiving Center) of the China Meteorological Administration is the task of the World Weather Research Program (WWRP) of the World Meteorological Organization (WMO) and the World Climate Research Program (WCRP), which is designed and implemented by the National Meteorological Information Center. This paper introduces the design and implementation of data exchange, data checking and processing, data archiving storage and data service portal in the construction of S2S data archiving center. Aiming at the problem of data exchange caused by the difference of S2S data configuration in various business centers, it is difficult to synchronize this problem. The data exchange is explained by the combination of data push based on FTP (file transfer protocol) and active data download based on ECMWF (European Center for Medium-range Weather Forecasts) WebAPI. Synchronization methods and strategies. Because of the huge amount of S2S data is difficult to efficiently manage the service, the unified data organization and storage rules have been designed to obtain the data storage location according to the data retrieval conditions, and to provide a convenient data retrieval and download service. Since the S2S data portal system of China Meteorological Administration opened to the public on November 15, 2015, the data portal system has registered and downloaded data from 300 users in more than 18 countries.
