WebThis index is used to estimate leaf chlorophyll content across a wide range of plant species. Having broad NIR and green wavelengths provides a better prediction of chlorophyll content while allowing for more sensitivity and a higher signal-to-noise ratio. Reference: Gitelson, A., Y. Gritz, and M. Merzlyak. The MERIS terrestrial chlorophyll index (MTCI) is calculated using three very specific red/NIR wavelengths (681.25, 708.75 and 753.75 nm). MTCI = (754nm−709nm) / (709nm−681nm) This index is more sensitive to high chlorophyll content compared to NDVI and is easy to calculate, which justifies … See more The chlorophyll index (CI) is applied to calculate the total amount of chlorophyll in plants.
