In order to guarantee basic meteorological service, enhance the frontlone staff’s management and maintenance capability, and improve observation data quality, a networkbased longdistance management and maintenance system for meteorological service is developed. The system adopts Windows Socket network technology and the customer/server mode and realizes the realtime communication and the longdistance screen sharing, document operation, system mode monitoring, and document automatic backup in P2P way. Through the wideband network, the system can carries out conveniently the longdistance management and maintenance of basic observation stations. The practice proved that the networkbased longdistant management and maintenance of meteorological services is an economical and feasible way, especially applicable to unattended observation stations.
