Measurements made above and below the canopy are used to determine the interception of light by the canopy at 5 zenith angles LAI is computed with this data using a wellestablished model of radiative transfer in plant canopies Novel Technology for N Janne Heiskanen, Miina Rautiainen, Lauri Korhonen, .
