Sentinel-2 Modified Chlorophyll Absorption Ratio (MCARI)

MCARI results from the following equation ( (VNIR - Red) - 0.2*(VNIR - Green) ) * (VNIR / Red) using Sentinel-2 Bands 5 (VNIR), 4 (Red) and 3 (Green). The MCARI is responsive to leaf chlorophyll concentration and ground reflectance. Generally high MCARI values indicate low leaf chlorophyll content. MCARI shows weakness in predicting low chlorophyll concentrations, especially the impact of soil signal limits its functionality. In consequence, MCARI should be interpreted together with NDVI or LAI.
