Leaf Area Index - (LAI)

LAI is the ratio of total upper leaf surface of green vegetation divided by the surface area of the land on which the vegetation grows. It represents the size of the interface between the plant and the atmosphere for energy and mass exchanges processes.

It is thus of prime interest for energy balance, photosynthesis, transpiration and litter production. It is a dimensionless variable [m2/m2], typically ranging from 0 for a bare ground to 6 for a dense forest.
