Abstract:According to the actual demand of provincial operation service, the provincial environment meteorological operation system was designed and developed. This paper described the system objectives, overall architecture, functional composition, and main key technologies. Based on the standardized message middleware technology, the key technologies such as unified grid data environment and intelligent grid forecast analysis service were constructed, and the operation system composed of integrated comprehensive monitor, forecast interactive analysis, product production and release was established. The operation system is stable and effective. The realization of the system promotes the standardization level of operation services and improves the guarantee ability of ecological environment meteorological services.
