Spring melt pond fraction in the Canadian Arctic Archipelago predicted from RADARSAT-2
Melt ponds form on the surface of Arctic sea ice during spring, influencing how much solar radiation is absorbed into the sea ice–ocean system, which in turn impacts the ablation of sea ice during the melt season. Accordingly, melt pond fraction ( f p ) has been shown to be a useful predictor of sea...

Melt ponds form on the surface of Arctic sea ice during spring, influencing how much solar radiation is absorbed into the sea ice–ocean system, which in turn impacts the ablation of sea ice during the melt season. Accordingly, melt pond fraction ( f p ) has been shown to be a useful predictor of sea ice area during the summer months.
