Albedo Measurements - Climate Data Information

WebThe albedo of Earth’s surface varies from about 0.1 for the oceans to 0.6–0.9 for ice and clouds—meaning that clouds, snow, and ice are good radiation reflectors while liquid … Albedo is not directly dependent on illumination because changing the amount of incoming light proportionally changes the amount of reflected light, except in circumstances where a change in illumination induces a change in the Earth's surface at that location (e.g. through melting of reflective ice). That said, albedo and illumination both vary by latitude. Albedo is highest near the poles and low…
