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.
For this study it seemed appropriate to simply vary the earth's average global surface albedo from today's average. Surface albedo was varied from 0% (absorption of all solar radiation) to 25%. Surface temperatures would be expected to increase for low albedo and decrease for high albedo.
