WebJan 1, 2011 · Refinement of the Earth radiation model from constant albedo (ALB-3) to latitude-dependent albedo (ALB-4) or to CERES derived surface properties (ALB-5), on the other hand, does not have an important impact on the orbits. Obviously GPS satellites are high enough such that varying surface albedo is averaged out over the visible illuminated ... WebOf the solar radiation reaching Earth’s surface, some is reflected back into the atmosphere. Values of the surface albedo range as high as 0.95 for fresh snow to 0.10 for dark, organic soils. On land, this reflection occurs entirely at the surface. In water, however, albedo depends on the angle of the Sun’s rays and the depth of the water ... omarion vs mario live free
