The albedo, (Latin for white) is a measure of reflected sunlight. Charcoal has an albedo of 0,04; snow 0,9 The planet with the highest albedo is Venus, whereas Mercury is theâ¦ lowest.
However, the effect is not as strong as changes in the solar constant. The surface temperature reaches a maximum value of about 345K when all of the solar radiation incident upon it is absorbed at the surface (albedo=0%) and about 305K for an albedo of 25%.
