BackForward Variable: Normalised Difference Vegetation Index (NDVI)

Definition
Full name Normalised Difference Vegetation Index (NDVI)
Definition Difference between maximum (in NIR) and minimum (around the Red) vegetation reflectance, normalised to the summation. Representative of total biomass, supportive for computing LAI if not directly measured
Measuring Units % Uncertainty Units %
Horizontal Res Units km Vertical Res Units
Stability Units % (Stability /decade)
