WebThe ground albedo is defined as the ratio between downward irradiance and upward irradiance where the latter results from the diffuse reflectance of the Earth's surface. The ground albedo is generally wavelength dependent and varies with the type of surface. Vegetation strongly absorbs UV radiation.

"WebThe albedo refers to reflectivity of a surface. Lighter surfaces are more reflective than darker surfaces (which absorb more energy), and therefore have a higher albedo. At the poles, the ice, snow and cloud cover create a much higher albedo, and the poles reflect more and absorb less solar energy than the lower latitudes. " - Higher albedo results in a warmer ocean

Higher albedo results in a warmer ocean

WebAlbedo effect. The albedo effect is the ability that a surface has to reflect light. For example, the average albedo effect of the Earth is 0.3. The number shows that the Earth’s surface reflects about 30 % of the sun’s radiation. More so, a low albedo effect means that a surface absorbs the sun’s heat and contributes to a warmer planet. WebSea ice has a much higher albedo compared to other earth surfaces, such as the surrounding ocean. The ocean, for example, reflects only about 6 percent of the …
