A vertical profile of reflectivity has many applications for radar-derived products. For example, a VPR identified as tropical in nature is used to invoke a tropical Z-R for precipitation estimates. Two types of VPRs are computed - one based on the 3D reflectivity field and the other based on individual tilts. Recent RAP model +10C, 0C, -10C and -20C are indicated.

TIP: If a circle is hollow (no VPR) go back in time to find the most recent detection.
Vertical profile of reflectivity for KVNX
This Vertical Profile of Reflectivity is derived from vertical columns within the 3D reflectivity field between 20 km and 80 km range. 3D Mosaic VPRs are used only for determination of precipitation type and brightband top and bottom.
This Vertical Profile of Reflectivity is derived from individual tilts and is used for reflectivity adjustment.
