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. WebDFS5.2 gives lower ponded ice area than JRA-55 Formation of sea ice →flattening of the ITD Topo. redistributes the melt water over the newly formed thin ice categories => shallow but extended melt ponds over the sea ice. The effect of the ponds on the total sea ice extent is restricted to summer months.

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.
