Abstract Focusing on the bottleneck of multisource data fusion in marine ecological disaster early warning,and combining relevant business practices in Shandong Province,a comprehensive data assimilation technology system tailored to the characteristics of observation instruments has been constructed.Through the path of "dynamic ocean element library intelligent grid assimilation early warning effectiveness evaluation",a multisource data quality control process has been formed,and the physical constrained neural network and multiscale nested assimilation method are applied in a collaborative manner.Taking actual cases as verification objects,the results show that this system can improve the timeliness of early warning to 72 hours,with an early warning accuracy rate of 88.4%,significantly enhancing the precise early warning and emergency support capabilities for ecological disasters.
