Abstract: Meteorological data is the foundation for conducting weather forecasting and meteorological services. There is a lack of effective means of data monitoring at the city and county levels after the provincial meteorological data transmission is switched to CIMISS (China Integrated Meteorological Information Service System), this paper provides an overall design scheme, proposes a method of monitoring log collection based on time unit offset, and then completed database design scheme and platform display design. The monitoring platform uses MVC framework, HTML, AJAX, and other technologies to realize the monitoring and quality statistics of meteorological data. The platform aims at three levels of users in provinces, cities,and counties, and provides reliable technical support for improving the transmission quality of provincial meteorological data.

Key words: meteorological observation data, transmission monitoring, quality statistic, time unit offset
