This satellite picture was taken on January 28, 2002 in the midst of the Icelandic winter. Notice that the southwestern area of Iceland has less snow than the greater part of the island. The Gulf Stream of the Atlantic Ocean swirls around southwestern Iceland and moderates its climate. Notice also the cloud of dust being carried off the southern coast by the winds. The coasts of Iceland can be very windy at times. Compare this picture with the similar picture of Iceland in summer.
This picture was taken by MODIS (Moderate Resolution Imaging Spectroradiometer),which is the key instrument aboard NASA's Terra (EOS AM-1) satellite. The original picture and two higher-resolution versions of this picture can be found at the NASA Visible Earth website.
