WebApr 11, 2024 · Accurate simulation of sea ice is critical for predictions of future Arctic sea ice loss, looming climate change impacts, and more. A key feature in Arctic sea ice is the formation of melt ponds. Each year melt ponds develop on the surface of the ice and primarily via affecting the albedo, they have an enormous effect on the energy budget and … WebMay 11, 2024 · Abstract. Melt ponds on sea ice play an important role in the Arctic climate system. Their presence alters the partitioning of solar radiation: decreasing reflection, increasing absorption and transmission to the ice and ocean, and enhancing melt. The spatiotemporal properties of melt ponds thus modify ice albedo feedbacks and the mass …

WebOct 31, 2015 · Bare, melting ice had peak transmittance in the range of 0.05–0.3. Ponded ice had peak transmittance from 0.25 to about 0.73. Peak values typically occurred somewhere between wavelength 470 and 500 nm. As was seen for the spectral albedo, ponded ice spectral transmittance shows more variability than bare ice transmittance.

WebOct 31, 2015 · In contrast, ponded ice absorbs or transmits to the ocean more than three-quarters of the incident sunlight. Characterization of the heat balance of a summertime ice cover is largely dictated by its pond coverage, and light transmittance through ponded ice shows strong contrast between first-year and multiyear Arctic ice covers.
