Below is a snippet of NMDA and NTDA detections. This area corresponds to the white rectangles in the upper left panels of the figure above.  The columns are labelled by elevation slice. There’s a lot going on here: unambiguous range issues, beam blockage at lower elevations, and a very strong Updraft/Downdraft Convergence Zone (UDCZ) that is also producing noisy velocity data at the UDCZ interface (ref. Spectrum Width in bottom row).
