ARVI is most useful in regions of high atmospheric aerosol content. It uses blue light reflectance measurements to correct for the atmospheric scattering effects, that also influence reflectance of red light.
General formula:
(NIR - RED - y * (RED - BLUE))/ (NIR + RED - y(RED-BLUE))*
Values description: The range for an ARVI is -1 to 1 where green vegetation generally falls between values of 0.20 to 0.80.
