There are only some (ALB_IMPROAD_DIF, ALB_IMPROAD_DIR, ALB_PERROAD_DIF, ALB_PERROAD_DIR, ALB_ROOF_DIF, ALB_ROOF_DIR, ALB_WALL_DIF, and ALB) in the input data of the model _WAL L_DIR) about the albedo property, so how do I see the actual albedo of the entire surface at the time of model input? How should I calculate or output this variable? I really need this variable information and look forward to your help!
