The China Meteorological Administrator (CMA) offers varieties of meteorological data to the general office of the State Council regularly. Since the rules of meteorological data filenames changed and the way of monitoring became unsuitable to operators, a new system is designed and developed to address the related problems. The new data collection and distribution functionalities can solve such issues as the illegal file filtering and figuration flexibility; the upgrade monitoring system can meet the operational needs of data retrieval, problem alarm, and time efficiency calculation; and the expanded data download service is more convenient for the operators. The loose coupled structure of data dissemination and monitoring functions is designed to strengthen the reliability and scalability. After half a year running stably, it is shown that the system can meet the requirements and provides effective support in flooding season.
