Earthâs Albedo and Global Warming This interactive activity adapted from NASA and the U.S. Geological Survey illustrates the concept of albedoâthe measure of how much solar radiation is reflected from Earth's surface. The balance between the amount of solar radiation reflected and absorbed by Earth's surface plays an important role in regulating global temperature.
Because albedo is the ratio of all reflected radiation to incident radiation, it will include both the diffuse and specular radiation reflected from an object. It is, however, common to assume a surface reflects in either a totally specular manner or a totally diffuse manner, as this can simplify calculations.
