Albedo at high angles of incident light such as those that occur on the illuminated side of Earth near the terminator (early morning, late afternoon, and near the poles). However, as mentioned above, waviness causes an appreciable reduction. Because light specularly reflected from water does not usually reach the viewer, water is usually considered to have a very low albedo in spite of its high reflectivity at high angles of incident light. Note that white caps on waves look white (and have high albedo) because the water is foamed up, so there are many superimposed bubble surfaces which reflect, adding up
Cloud albedo Cloud albedo Cloud albedo is a measure of the albedo of a cloud. Higher values indicate that a cloud reflects a larger amount of solar radiation and transmits a smaller amount of radiation. Cloud albedo depends on the total mass of water, the size and shape of the droplets or particles and their distribution in space. Cloud albedo, along with the greenhouse effect of clouds, strongly influence the Earth's energy budget. Thick clouds (such as stratocumulus) reflect a large amount of incoming solar radiation, meaning they have a high albedo. Thin clouds (such as Cirrus) tend to transmit most solar
