Abstract: As an important part of meteorological information, weather modi fication data are characterized by application focus, real time, and continuous integrity. The requirements for weather modi fication data range from weather forecasts, data analysis, monitoring and evaluation, to scientific research. At present, the data used by weather modification have not yet sorted into the standard. It is necessary to make a reasonable classi fication and coding standard, to establish a standardized management.It is needed to modernize the weather modi fication. This paper focuses on the research of the meteorological data for weather modi fication and the whole life cycle of the equipment and ammunition. The data should be classi fied by the operation phase, purpose, equipment category, operating area, be referred meteorological data classification and coding, be suitable for the collection, processing, storage, archiving and service process of the weather modi fication data.
