Abstract:
In order to meet the requirements of meteorological departments for efficient management and sharing of meteorological government administration data, solve the problems of difficult communication, sharing and collaboration of data, and promote the integration of meteorological government administration data into the national integrated government big data system, China Meteorological Administration designs and builds the meteorological department’s first centralised and unified government administration data centre, which is “one level of concentration and four levels of application,” relying on the national-level meteorological proprietary cloud platform, and directly supporting meteorological government administration and business applications. This article analyses the current status, existing problems and construction needs of meteorological department government administration data, introduces the core architecture design, main business functions, the key information flow, the government administration data classification and hierarchical data system based on the characteristics of meteorological government administration data, key implementation technologies, and application effectiveness of the system. The implementation of the system adopts a series of advanced information technologies, including support for multi-source heterogeneous data aggregation, policy-based data cleansing and integration governance, globally unified data service and interface management, full-text search based on the open-source ElasticSearch engine, message-driven management application collaboration, data synchronisation in the master and standby centres, etc. The system started construction in 2019, and after more than two years of research and development, it completes the development of system software functions, establishes a data collection, data storage and data update mechanism, provides unified data sharing services, and continues to carry out the aggregation and governance of government administration data resources. It builds data applications such as office management, forecasting, human resources management, technology management, forecaster team portraits, full-text retrieval, business collaboration, comprehensive management decision-making analysis, etc. As the system is put into business applications, government administration data of the meteorological department are standardised, managed and effectively utilised, establishing a data resource directory of 12 first-level categories, 72 second-level categories, and 357 types of government administration data, completing the collection and storage of 237 types of data, releasing a total of 30 data interfaces in 20 categories, implementing 72 types of government administration data sharing applications within the meteorological department. Master data such as personnel, institutions, administrative divisions, seasonal holidays, and public roles provide real-time data services for more than 200 applications of the meteorological department. As a digital base for the digital transformation and upgrading of government administration of the meteorological department, the system provides “one-stop” government data management and sharing application services for the four-level meteorological departments at the national, provincial, city and county levels after its completion, and plays an essential role in effectively supporting China Meteorological Administration’s office management, scientific decision-making and performing public functions.
