Abstract

We measured the angular distribution of spectral scattering properties of Scots pine shoots. We were able to scale the photochemical reflectance index (PRI) between two canopy structural levels using photon recollision probability. We found non-negligible anisotropy in shoot PRI possibly caused by reflectance of the needle wax coating.
