VVP (Velocity Volume Processing) Provides an estimate of the wind profile up to a certain height EHT (Echo Height Top) Gives a representation of the height to which the top of the clouds extend. PPI (Plan Position Indicator) Gives A representation of the cloud echoes in a horizontal plane. SRI (Surface Rainfall Intensity) An estimate of rain intensity associated with different echoes. ` MAX (Maximum Precipitation) Shows a 2-dimensional (2D) flow for the horizontal and vertical profile of the clouds.
