In order to unify the meteorological data retrieval modes of meteorological applications, regulate the meteorological data operational environment, an standardized meteorological data service interface is designed and developed based on Spring Boot and Spring Cloud microservice frameworks according to the meteorological informatization action plan of China Meteorological Administration (CMA) and Zhejiang Provincial Meteorological Service. The standardized meteorological data service interface complies with meteorological informatization standard system of CMA, stores all kinds of meteorological data in the resource pool after data be collected and processed, then publishes all data through RESTful API, provides standard data retrieval services for all kinds of meteorological applications in Ningbo. This interface has changed the old mode of meteorological applications (direct accessing database), reduced the cost of application development, also enhanced the ability of operation and maintenance department to monitor and manager meteorological data retrieving. This paper presents the design and development process of the standardized meteorological data service interface and describes in detail the interface specifications, operational processes, and critical technologies in the development cycle.
