CVI - chlorophyll vegetation index. It has an increased sensitivity to the content of chlorophyll in the deciduous cover. It is used from the beginning to the middle of the crop growth cycle for a wide range of soils and sowing conditions by analyzing a large set of synthetic data obtained using the reflection model of the leaf surface. The increased sensitivity of the index to the concentration of chlorophyll in the leaf is due to the effective normalization of various LAI values obtained with the introduction of red and green colors.

CVI = NIR * ( RED / GREEN ^ 2)
