In the observation data from the nextgeneration weather radar adopting the mode2 precipitation observation, there are about 240 basic data and 7200 data products for one day. Because of the different formats between the file names of the basic data and data products and the file names used in data compilation, the manual compilation meets great difficulty. The key techniques of the radar data compilation and processing system and the solutions to radar data compilation are introduced systematically, in which the naming of the files can be automatically conducted in batches and by adopting the technique of the wizard task processing, the automation, batch processing, routinization, and standardization of radar case data compilation can be realized.
