Web12. apr 2024 · This reflectivity is called albedo. The temperatures on most of the Moon's surface are too extreme for water or ice to exist, ranging from a maximum of 7270C (2610 F) at lunar noon to a minimum of -1730C (-2790F) just before lunar dawn. Temperatures in permanently shadowed areas near the lunar poles, however, may consistently be as low … WebAlbedo is the measurement of reflectivity of sunlight by any object (Hall and Qu, 2006 ). Objects reflecting more sunlight have high albedo while those reflecting less have a low albedo. It is measured on a scale of 0–1 or given in percentage with 1 being a perfect reflector (100%) and 0 (0%) absorbing all incoming light. Web19. máj 2024 · But it turns out forests can warm the planet, too, primarily by changing the reflectivity, or albedo, of land surfaces. Gleaming surfaces such as fresh snow have an albedo of 0.8 to 0.9 (on a scale from zero to one), meaning they bounce a lot of solar energy back into space.
