Abstract：The development of high-precision,high-quality,and spatiotemporally continuous multi-source meteorological data fusion grid-based products using data assimilation and data fusion techniques as well as multi-source observation data has become a key focus of meteorological data research.Based on the LAPS model for multi-source data fusion,this paper establishes a provincial analysis system for Henan Province.By integrating ground,sounding,and radar data,grid-based observation products for Henan Province is produced,including precipitation fusion analysis products,three-dimensional grid-based observation products(temperature,wind,relative humidity),and refined grid-based soil moisture data products.Systematic evaluation is conducted on the grid-based observation products obtained from the national and provincial observatories,and the observation data at any time and in any region is evalu-ated based on conventional evaluation,characteristic evaluation,and refined evaluation schemes,which provides more accurate and refined evaluation conclusions.Based on the B/S architecture and adopting the technological route of service-oriented architecture,a multi-source meteorological data fusion system platform for Henan Province has been built,achieving the display and evaluation of national and provin-cial grid-based observation products and fully leveraging the application value of gridded observation and fusion data products.
