Abstract: This paper briefly describes the designs and implements a new type of command system for weather modification operation in Northwest China, which is named Smart Platform of Analysis and Cloud sEeding (SPACE-NW), by adopting the “cloud and terminal” system architecture mode. Combined with the latest information technology and a big meteorological data cloud platform named Sky Engine, SPACE provide comprehensive software support for all kinds of weather modification operations. Based on the Sky Engine platform foundation, the system puts forward a universal “4C + ABC” framework under the “cloud and terminal” of weather modification to realize the deep integration of data environment, data analysis, automatic production, and processing pipeline for meteorological products. It has solved the many key problems of various data collection channels, nonuniform standards, lack of openness of the system, low timeliness, and poor information circulation and exchange. The system has been deployed in takes the lead in Northwest China, and play typical demonstration role in the deep integration of provincial weather modification operations and Sky Engine platform.
