DOW6 VAD Winds at Snowbank
https://data.eol.ucar.edu/dataset/534.055

Summary
The dataset consists of vertical profiles of horizontal winds derived from
radar Plan Position Indicator (PPI) scans conducted at a 17° elevation angle.
In cases where 17° data were unavailable, the highest available elevation
angle was utilized. The wind profiles were obtained using the Vertical Azimuth
Display (VAD) technique, which involves measuring the radial velocity of
targets at various azimuth angles and applying a least square fitting
procedure to extract the horizontal wind speed and direction as a function of
altitude. This method assumes that the wind field is horizontally homogeneous
over the radar sampling volume. For more details on the VAD technique, refer
to Browning and Wexler (1968).
