〉Metallic Reflection. When a light beam encounters a material, radiation can be absorbed or reflected by the surface. Metals are known for having high reflectivity, which explains their shiny appearance. Since the reflectance of light by metals is high their absorption is low because the sum of both must correspond to 100% of the incident light.

〉Abstract. The Greenland Ice Sheet is losing mass at a significant rate, driven in part by increasing surface-melt-induced runoff. Because the ice sheets surface melt is closely connected to changes in the surface albedo, studying multidecadal changes in the ice sheets albedo offers insight into surface melt and associated changes in its surface

〉2017523ヂ 1. Introduction. The seasonal and interannual variability of melt on glaciers and ice sheets is primarily driven by the absorption of shortwave radiation at the surface (Braithwaite and Olesen, 1990; Munro, 1990; Arnold et al., 1996; Brock et al., 2000; van den Broeke et al., 2008).Albedo modulates the fraction of absorbed shortwave radiation and
