Visible Atmospherically Resistant Index
Description
The Visible Atmospherically Resistant Index (VARI) is designed to emphasize vegetation in the visible portion of the spectrum, while mitigating illumination differences and atmospheric effects. In other words it is used to estimate the fraction of vegetation with a minimal sensitivity to atmospheric effects (Mokarram et al., 2016).
