In order to change the distributed status of the meteorological service platform, based on the integration of the self-built service platforms including meteorology, climate, observation and service, National Meteorological Information Center (NMIC) constructs National Meteorological Service Platform (NMSP). NMSP is a unified national meteorological service platform to provide browsing, searching and displaying of observation, weather forecasting, warning information, historical climate data and network information. NMSP uses the MVC design pattern. For adapting the characteristics of meteorological application, above J2EE application framework (Struts + Spring + Hibernate), NMSP encapsulates data exchange module which improves flexibility and efficiency of the system development. On March 2015, NMSP (version 2.0) has been on operational running, which covers six core sections, nearly 100 sub-modules, 2000 kinds of service products. It plays an effective supporting role on various types of meteorological service.
