China's first precipitation measurement satellite has been successfully launched in April 2023, combining active and passive microwave instruments dual-frequency precipitation measurement radar and microwave imager to carry out high precision precipitation detection. In view of the limited coverage of precipitation measurement radar, the radar reflectivity factor data of wide swath radar is developed by using the microwave radiometer imager data of the same platform and the deep learning model, and the coverage of 2.67 times the width of precipitation measurement radar is achieved, which significantly increases the observation range of precipitation measurement radar. Taking Typhoon "Tali" in 2023 and extreme short-time heavy precipitation in North China as examples, the application potential of the wide swath results generated by the service is analyzed. The calculation result of the radar re-flectivity factor of wide swath radar is consistent with that of ground based radar, which has a good reference in practice. In the ground system operation scheduling, in order to support the continuous high-timeliness calculation of wide swath radar reflectivity factor data, this paper designs the wide swath radar reflectivity factor operation flow, comprehensively considers the resource con-sumption, timeliness and reliability of the operation implementation, and proposes the best data-driven operation scheduling strategy,which can effectively reduce the running time and improve the timeliness.
