Path-CVP (pCVP) – polarimetric radar data snapshot along the predefined path based on Columnar Vertical Profiles

Abstract. Recently introduced Columnar Vertical Profiles (CVPs) arrange polarimetric radar data collected via plan position indicator (PPI) scans in height vs. time format at a single location. A novel method for polarimetric radar data processing and visualization, path-CVP (pCVP), is introduced. It represents radar data in height vs. location format at the time of a completed radar volume scan. pCVP, an offspring of CVP, is a single-radar-volume time snapshot of the polarimetric radar data along an arbitrary or predefined path with high spatial resolution. Multiple examples from S-band WSR-88D radars in the NEXRAD network demonstrate the potential usage and advantages of the technique. Monitoring and quantifying instantaneous weather conditions with polarimetric radar along motorways, mountain overpasses, and aircraft paths during descent and ascent from the runway, as well as tornado location diagnostics, are potential benefits of the novel technique. However, the increasing distance from the radar and the size of the area used for CVP spatial averaging may need to be adjusted based on user needs.
