MERIS Terrestrial Chlorophyll Index (MTCI)

Meris Terrestrial Chlorophyll Index (Dash and Curran, 2004)

It is calculated as the normalized difference between Sentinel Bands 8A (NIR) 4 and 5. It makes use of bands in the so-called “red edge”, which is a spectral area across the red and the NIR. It is sensitive to chlorophyll content, and it is used to monitor canopy senescence and phenology.

The index formula is defined as:
(B8a - B5) / (B5 - B4)
