Abstract: Attenuation is one of the main factors that affect the data quality of X-band radars, which directly affects the application effectiveness of X-band radars in severe convection monitoring and early warning. Based on the analysis of different radar attenuation correction methods, both domestic and abroad, this study improves one of the radar attenuation correction methods that utilizes mutual correction among different radars in the radar network, and establishes a reflectivity factor attenuation correction method that is suitable for networked X-band radars. With the new method, the correction error is minimized through continuous iterative computation. The correction outputs are compared with original radar data and results using the differential phase (\phi __\rmDP) correction method as well as observations of the Beijing S-band radar. It is found that the attenuation correction is more effective for the X-band radar echoes that penetrate heavy rainfall or at long detection distance, and the corrected echoes are consistent with the S-band radar observations.
