Description
MCARI/MTVI2 is a ratio index that combines the Modified Chlorophyll Absorption Ratio Index (MCARI) with the Modified Triangular Vegetation Index 2 (MTVI2). This combination provides improved sensitivity to leaf chlorophyll content while reducing the influence of leaf area index variations, making it particularly useful for agricultural applications.
