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.
The albedo over snow and ice can be as high as 90% and as low as 5% over a forest. Deserts and areas of sparse vegetation typically have an albedo of 15-25%. Thick, widespread clouds produce an albedo of 70% or more. The average surface albedo of the earth under today's conditions has been estimated to be about 13%. This average takes into consideration the snow cover in the polar regions, forest and other vegetation on the continents, the oceans, and average diurnal and seasonal solar zenith angles.
