• vegetation index
• MERIS terrestrial chlorophyll index (MTCI)
• modified MERIS terrestrial chlorophyll index (M-MTCI)
• double-peak canopy nitrogen index (DCNI)
• chlorophyll content

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.
