摘　　要：作为气象数据和产品分发的主要渠道,中国气象局气象资料卫星数据广播系统为国内超过2400个各级气象部门、亚太地区气象用户及其他行业用户提供气象观测资料和气象服务产品。由于广播的气象数据种类众多,数据属性不一等特点,导致对气象数据的精细化监控力度不足。为解决上述问题,提出一种基于元数据管理的气象数据精细化监控方法。在建立气象广播资料元数据的基础上,针对重点气象资料进行数据播发规律研究,采用正则表达式、监控时间窗等指标进行判别计算,实现文件级广播监控,从而提升系统综合监控能力,建设完成中国气象局卫星广播精细化监控系统并投入使用。实践证明,精细化监控系统能够满足卫星广播的精细化监控需求,具有可扩展性与可维护性,保障广播系统的正常运行。As the main channel for distribution of meteorological data and products,the China Meteorological Administration Satellite Broadcast System provides meteorological observation data and meteorological service products for more than 2400 meteorological departments at all levels,meteorological users in the Asia-Pacific region and other industry users.Due to the various types and different attributes of meteorological data,the refinement monitoring of meteorological data is insufficient.To solve the above problems,a refinement monitoring method of meteorological data based on metadata management is proposed.Based on the establishing meteorological broadcasting metadata,data broadcast law is studied for the key meteorological data.Regular expression,monitoring time window and other indicators are used for discriminant calculation.To achieve file-level broadcast monitoring and improve the comprehensive monitoring capacity of the system,the China Meteorological Administration Satellite Broadcast Refinement Monitoring System was completed and put into use.Practice has proved that the refinement monitoring system,which is scalable and maintainable,meets the refinement monitoring requirements of satellite broadcasting and ensures the normal operation of broadcasting system.
