A straightforward technique for VPR adjustment based on the analysis of accumulated pseudoCAPPI data at two different heights is proposed. The extracted VPR gradient is used to perform a range and azimuth dependent adjustment using a purely analytical expression. The application of the dual-CAPPI technique is illustrated using a case of stratiform precipitation and a strong bright band interference. A preliminary verification indicates that the dual-CAPPI technique performs rather good for cases with stratiform precipitation. The development of the dual-CAPPI technique will be continued by a semi-operational implementation and a more detailed verification.
