Fig. 2: Radiative effect of meltwater ponding on the Greenland Ice Sheet during the summers of 2018 and 2019 by elevation.
From: Meltwater ponding has an underestimated radiative effect on the surface of the Greenland Ice Sheet
a Proportion of spatial albedo variability caused by meltwater ponding during Jul 29–Aug 5, 2019, colored by length scale. “Length scale” represents the side length of the search window used for quantifying albedo variability (see Methods). b Area of meltwater ponding in a warm (2019) and cool (2018) summer. c Radiative effect of meltwater in a warm (2019) and cool (2018) summer. d Radiative effect of meltwater in a warm (2019) and cool (2018) summer, converted to units of energy absorbed by the ice sheet per day. e Regional radiative effect of meltwater ponding in North and Southwest Greenland in 2019. The dashed lines represent the elevations of our field sites in Southwest Greenland that we surveyed by drone. f Sensitivity of the radiative effect caused by meltwater ponding to near-surface air temperatures.
