Abstract

Modified MERIS Terrestrial Chlorophyll Index (M-MTCI) was developed based on modifications of MTCI. M-MTCI is better than MTCI and Double-peak Canopy Nitrogen Index (DCNI) on aspects of chlorophyll content retrieval precision (when LAI >1). Besides M-MTCI has better chlorophyll and LAI effects separation than MTCI. Validation by numerical simulations and in-situ measurements shows that M-MTCI is a reliable VI for chlorophyll content retrieval. Therefore, M-MTCI is a prosperous VI for chlorophyll content monitoring applications.
