The United Kingdom was uncommonly cloud free on March 29, 2002, as can be seen in this SeaWiFS image. Much of mainland Western Europe also had clear skies, albeit somewhat hazy. At the southern extreme of the image, much dust is still visible in the air over northern Algeria and moving northward toward Europe.
Two low-pressure systems—one centered just northeast of Cape Ortegal, Spain, and the other over the Norwegian Sea—can be seen moving in from the west. (The northern spiral looks horizontally stretched because of the projection used to make this scene.)
