Short summary

This paper proposed three methods for determining the reflectivity bias of single polarization radar using dual polarization radar reflectivity and disdrometer data (i.e., the equidistance line, overlapping area, and disdrometer methods), and we evaluated for two low-pressure rainfall events that occurred over the Korean Peninsula on 25 August 2014 and 8 September 2012. Overall, the most accurate rainfall estimates were obtained using the overlapping area method to correct radar reflectivity.
