Optical study of surface melting on ice
WebAbstract. Melting of the Greenland Ice Sheet (GrIS) is the largest single contributor to eustatic sea level and is amplified by the growth of pigmented algae on the ice surface, which increases solar radiation absorption. This biological albedo-reducing effect and its impact upon sea level rise has not previously been quantified. Here, we combine field … WebJun 13, 2024 · Optical measurements on melt ponds with open water surface were the idealized validation data for this study. However, during in situ observations, some melt ponds were covered by snow, which were removed as a result of great difference between the model and the measured data. There were also some melt ponds with ice lid on the …
