Reflectivity of earth
WebLand reflects 10–25% of sunlight, and clouds reflect around 50%. Thus, the part of Earth where it is daytime and from where the Moon is visible determines how bright the earthshine on the Moon appears at any given time. Earthshine reflected from the Moon during conjunction with Venus (left)
Reflectivity of earth

WebRepresentative spectral reflectivity measurements for common earth surface features are given in Fig. 1. Soil reflectivity in general increases monotonically with increasing wavelength to about 1.3 μm and then decreases with sharp dips at 1.4 μm and 1.9 μm because of absorption by soil water. WebAveraged annually over Earth’s entire surface, the Sun provides about 345 watts per square metre of energy. About 30 percent of this energy is reflected away to space and is never used in the Earth-atmosphere system. Of that which remains, a little less than 1 percent (3.1 watts per square metre) accelerates the air by generating winds.
WebMay 14, 2024 · This reflectivity, called albedo, is one key way Earth regulates its temperature – if Earth absorbs more energy than it reflects, it gets warmer, and if it reflects more than it absorbs, it gets cooler. The picture becomes more complicated when scientists bring the other wavelengths into the mix. In the near-infrared part of the spectrum ...
