超大城市观测数据系统平台设计与实现

为收集管理应用新型地基遥感设备观测的海量、多源、实时数据，中国气象局气象探测中心设计并搭建了超大城市观测数据系统平台。系统基于主流Web开发技术和分布式列存储集群方式MySql数据库，具备数据实时传输、监控、存储、分析、显示和共享等功能，实现了新型地基遥感观测数据管理规范化、产品服务多样化、资料共享便捷化。该系统平台既提高了新型地基遥感设备数据的支撑保障能力，同时分钟级廓线数据产品满足了短临天气预报对实时数据的高时效需求。目前，平台已在部分城市中推广应用，为地基遥感设备业务化运行提供全面的平台支持。

Design and Implementation of Megacity Experiment on a Meteorological Observation Platform

The Meteorological Observation Center of the China Meteorological Administration (CMA) has carried out a vertical comprehensive meteorological observation experiment of megacities. In order to collect and manage a large amount of long term observation data with new ground based remote sensing equipment, a megacities observation data system platform has been designed and built. Based on Web technology and the MySQL database, the system has the functions of real time data transmission, monitoring, storage, analysis, display and sharing. It standardizes the management of new remote sensing observation data and makes product diversification convenient to share. The system improves the data support ability of the new remote sensing equipment and the minute profile data products meet the high timeliness requirements of the short term weather forecast and nowcasting for real time data. At present, the system has been popularized and applied in some cities to provide comprehensive platform support for the operational operation of ground based remote sensing equipment.
