Plain Language Summary: An efficient, practical post-processing algorithm was developed for the quality control of dual-pulse repetition frequency (dual-PRF) Doppler velocity data observed in plan position indicator (PPI) mode. The proposed algorithm relies on the local continuity of velocity data, as do most of the preexisting algorithms. Its uniqueness, however, lies both in the preparation of more reliable reference velocity data and its applicability to PPI data at higher elevation angles. The performance of the algorithm is demonstrated by its application to observed data from C- and X-band Doppler radars. As shown in Fig. 1, the algorithm completely corrects the errors in the observed data at high elevation angle without affecting data regarded as good quality. This algorithm is practical, efficient, and not time consuming. It may be of great help in the derivation of accurate wind information from dual-PRF Doppler velocities.
 

Highlights:

• New algorithm for the determination of more reliable reference velocity data for correction.
• High performance even at higher elevation angles.
• Efficient practical algorithm.
