Sea ice concentrations in the Weddell Sea: A comparison
[1] The sea ice fraction in the interior of the pack, especially in winter, is important for climate studies and for validation of sea ice models. When ice concentration is high, a difference of only a few percent in ice fraction can have a major effect on the ocean-air fluxes. Satellite estimates o...
