What Is Vertically Integrated Liquid?
A radar estimate of how much water and ice a storm is holding. High values suggest heavy rain or hail. In technical terms: A WSR-88D product estimating total liquid water content in a column, in kg/m², by integrating a reflectivity-to-liquid-water relation through the depth of the echo; values depend strongly on airmass, with high values relative to the environment suggesting large hail.
Also called: VIL
Vertically Integrated Liquid In Plain English

The Technical Definition
A WSR-88D product estimating total liquid water content in a column, in kg/m², by integrating a reflectivity-to-liquid-water relation through the depth of the echo; values depend strongly on airmass, with high values relative to the environment suggesting large hail.
