Description

ARVI2 is an enhanced version of the Atmospherically Resistant Vegetation Index designed to be resistant to atmospheric effects while being more sensitive to a wide range of chlorophyll concentrations. It builds upon the original ARVI concept by Kaufman and Tanré, providing improved vegetation monitoring capabilities under varying atmospheric conditions.
