The warm surface water results in drier air and … 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.

WebSurfaces with high albedos include sand, snow and ice, and some urban surfaces, such as concrete or light-colored stone. Surfaces with low albedos include forests, the ocean, and some urban surfaces, such as asphalt. Albedo generally applies to visible light, although it may involve some of the infrared region of the electromagnetic spectrum.

Web31 de mar. de 2024 · Clouds high up in the atmosphere have the opposite effect: They tend to warm Earth more than they cool. High, thin clouds trap some of the Sun’s heat. This warms Earth’s surface. Wispy clouds high up in the atmosphere generally make an area warmer. Lower-altitude clouds tend to help an area cool off. Credit: NASA/JPL-Caltech

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.
