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
Surface Heat Budget of the Arctic Ocean that solar radiation is the dominant heat source to the surface. It accounted for the change in open ocean from a 5% maximum in June and the changes in albedo. Approximately 8% of incoming solar radiation was absorbed into the ocean through the ice. The scientists were able to define parameters for near-surface turbulence that characterize the degree to which air movement can cool or warm the surface of the ice, seasonally. In summer, the surface becomes rougher and slows down air flow. The lidar cloud measurements and balloonsonde temperature and turbulence data allowed scientific characterization of the role of
