[PPS02-P14] Numerical simulation on the albedo of rough surfaces
Keywords:albedo, rough surface, thermal evolution
We developed a new numerical model to simulate the image of a rough surface and by using the model calculated the bond albedo of the rough surface.
According to our model, even for the case with Lambertian polygons the bulk bond albedo depends not only on the roughness of the surface but also on the solar incident angle, because of heterogeneous distribution of irradiated area. In this presentation we will propose a new equation to calculate the bond albedo of a rough surface.
