Greenland Albedo Anomalies, Aug … WebSome of the lowest albedo features on the Ice Sheet are water-filled supraglacial stream channels, especially those with abundant deposits of consolidated cryoconite sediment. Because these sediments enhance melting by disproportionately lowering albedo, studying their spatial extent can provide a better understanding of Greenland’s contribution to … quay australia coffee runWebAlbedo is the proportion of incident light that is reflected away from a surface.. Diffuse reflection is the reflection of light in many directions, rather than in just one direction like a mirror (specular reflection).. In the case of ideal diffuse reflection (Lambertian reflectance), incident light is reflected in all directions independently of the angle at which it arrived. quay brewery
