The Meteorological Cloud Desktop System of CMA Meteorological Observation Center

The National-level Meteorological Observation Real-time Operation Platform was built by the CMA Meteorological Observation Center (MOC) In 2019, which integrated national real-time meteorological observation operations, research-oriented operations and external display. The real-time operation platform adopted the office form of the meteorological cloud desktop system, so that the operating system, applications and data were all centralized to the data center for unified management. The system was based on the core technology of Independent Computing Architecture (ICA) protocol and relied on the construction of servers, network devices and storage, and by means of distributed deployment and virtual architecture, the release and management functions were realized. NVIDIA vGPU was also applied in the system to release a VDI virtual design desktop based on GPU graphics, which satisfied the 3D modeling and CUDA computing needs of operating staff. At present, 80 cloud desktop systems had been built on the real-time operation platform, and customized operating systems and supporting software applications had met the requirements. The internal and external network cloud desktop physical isolation completely solves the problems of traditional office equipment decentralized management, low data security factor, high operation and maintenance cost, and inability to achieve mobile office. The technical advantages and architecture design of the meteorological cloud desktop system, the design and deployment process of the system and the key technologies involved in the operation application were described in detail in this paper.
