Description

TCARI/OSAVI is a combined vegetation index that integrates the Transformed Chlorophyll Absorption in Reflectance Index (TCARI) with the Optimized Soil-Adjusted Vegetation Index (OSAVI). It is designed for accurate estimation of crop chlorophyll content while minimizing the effects of soil background and leaf area index variations.
