- Description
- The gaussian random sphere (GRS) or spherical (SPH) particles were generated following a measured size distribution of SPIPA-B. The size was scaled to different mean diameters. They were packed to a volume fraction of 20% or 50% in a semi-infinite medium. The reflectance factor was simulated for i=0° e=25°.
