摘要
针对大数据环境下,气象档案数据面临数据来源复杂、数据质量不能保障和数据不能有效应用等问题,根据元数据自身特性,文章从档案数据管理及应用角度出发,设计了气象档案数据元数据,并以原始格式气象多普勒雷达基数据元数据为实例,具体阐述了元数据描述过程,探讨了元数据库及元数据知识图谱的构建方法,以及在气象档案数据管理及应用服务中的作用。旨在为当前气象档案数据管理及应用提供参考。
In the big data environment, meteorological archives data faces the problems such as complex data sources, insecure data quality and ineffective data application.According to the characteristics of metadata, this paper designs the metadata of meteorological archive data from the perspective of archive data management and application.Taking the original format of base data metadata for meteorological Doppler radar as an example, the metadata description process is described in detail.This paper discusses the construction method of metadata base and metadata knowledge map, and its role in meteorological archive data management and application service.The aim is to provide reference for the management and application of current meteorological archives data.
