NASA’s EOSDIS Worldview gives stunning pictures.  This one, of polar regions north of Greenland appears to show the ice edge with cold air streaming off over the sea forming ever deepening cumulus.  This edge seems almost too bold.

Check on MODIS (Dundee) Channel 6 (snow/cloud discrimination 1628-1652nm) and Channel 22 (surface cloud 3.929-3.989µm) seems to back this analysis up; temperatures of cloud tops over the sea being colder than the ice.  Fractures and polynyas in ice, much loved by cold war submariners, show up with amazing clarity.
