Overview

DESCRIPTION: Like Base Reflectivity, Base Velocity is a base product measured by the radar. Base Velocity is the average radial velocity of the targets in the radar beam at a given location. Radial velocity is the component of the target's motion that is along the direction of the radar beam. Positive values (warm colors) denote out-bound velocities that are directed away from the radar. Negative values (cool colors) are in-bound velocities that are directed towards the radar.

PRODUCTS: There are four (4) Base Velocity NIDS products, available in both precipitation and clear-air modes:
