Abstract:
Clouds are an important part of the earth system, which can affect the radiation balance of the earthatmosphere system by affecting atmospheric radiation transmission. At present, the information obtained from threedimensional cloud observation has certain limitations, so it is necessary to obtain more accurate threedimensional cloud information by using multisource observation data merging analysis. Based on the successive correction method, 〖JP2〗the ThreeDimensional Cloud Merge Analysis Operation System (3DCloudAV1.0) integrates multisource data such as numerical forecast products, geostationary meteorological satellite observation, meteorological radar observation to produce the realtime 0.05°/h threedimensional cloud merging analysis product covering China and its surrounding areas (0°-60°N, 70°-140°E), which is distributed to the national and provincial meteorological departments through the China Telecommunication System. The modular system framework is considered in the operation system design and construction process, and the fault tolerant functions such as ECFlow scheduling process realtime monitoring and automatic restarting are developed, which effectively improves the stability and reliability of the operation system. Evaluations show that through merging multisource observation data, the threedimensional cloud merge analysis product can describe cloud the top, inside and bottom information more accurately.〖JP〗
