Bands Used: 4

Description

MCARI/OSAVI combines the Modified Chlorophyll Absorption Ratio Index (MCARI) with the Optimized Soil-Adjusted Vegetation Index (OSAVI). This ratio index is designed to estimate leaf chlorophyll content while minimizing the confounding effects of leaf area index and soil background reflectance.
