Snow and ice albedo is a critical geographical indicator that reflects climate change on Earth. Quantifying the albedo in Greenland ice sheet, which is extensively covered with snow and ice, is key to studying changes in the energy budget in the Northern Hemisphere. Earth observation satellites have been regularly providing surface albedo products. However, optical satellite-derived albedo products have many voids due to the persistent cloud cover over the Greenland ice sheet. Consequently, seamless reconstruction of albedo on the spatial and temporal scales is essential. Surface albedo, as a geographical element, is spatially and temporally correlated. In addition, the broadband albedo of snow and ice is significantly modified by changes in the spectral distribution of solar irradiance caused by clouds. On the basis of such facts, this study proposes a reconstruction method for snow and ice albedo that …
