The upward transmission of meteorological data is the foundation of meteorological servicesTo satisfy the needs of stations for realtime upward transmission of meteorological data after the meteorological communication system switched to CTS (China Telecommunication System), this paper describes the the transmission procedure of upward meteorological data, proposes the ideas about the construction of the transmission monitoring platform for upward meteorological data, designs the platform architecture, synchronization strategy for transmission logs, and the personalized display data policyThis platform is implemented by the MVC framework, Quartz scheduler and jQuery Grid PluginThe function of realtime monitoring for upward meteorological data transmission is implementedThe statistical analysis for the transmission status is also provided in this platformThe error report can also be queried from this platformThis platform has been put into operation as a module of MOPS (Metrological Observation Platform for Station), and provides the support of the platform for improving the quality of upward meteorological data transmission
