On the remote sensing of oceanic and atmospheric convection in the Greenland Sea by synthetic aperture radar

, 2004
In this paper we discuss characteristic properties of radar signatures of oceanic and atmospheric convection features in the Greenland Sea. If the water surface is clean (no surface films or ice coverage), oceanic and atmospheric features can become ...
