The construction of the Atmospheric Observing System Operations and Monitoring system improved the capacity of operational supporting on the detection equipment of the integrated meteorological observation network. As a beneficial supplement to the monitoring system, a GIS application platform is constructed, which is oriented to meteorological observing based on ArcGIS Engine technology. The method of meteorological observing equipment monitoring is described emphatically, and several key issues about meteorological equipment monitoring based on C/S structure, such as data acquisition, data handling, map update, etc., are discussed. The system combines data retrieval, map display, equipment monitoring, statistic and analysis, and product release together, as well as the management of the observing station network. It realizes diversification, informatization, visualization, professionalization, and productization of meteorological equipment monitoring.
