As described in the introductory section, one of the first global measurements performed by orbiting radiometers was the estimation of … WebThe amount of energy reflected by a surface is called albedo. Dark colors have an albedo close to zero, meaning little or no energy is reflected. Pale colors have an albedo close to 100%, meaning nearly all the energy is reflected. Forests, for example, have an albedo of about 15%, which means that 15% of the sunlight that hit a forest is ...

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 ...
