Clouds surrounded Iceland on April 23, 2022, when the Moderate
Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Aqua
satellite acquired this gorgeous false-color image of the island
nation. Clouds are thickest over the North Atlantic Ocean, to the west
and south of Iceland and thin over the Greenland Sea (north) and the
Norwegian Sea (east). Parts of the western and southeastern coast also
wear a cover of cloud, primarily in the form of low cloud (fog) that
appears to fill the valleys. Most of the sky over the mainland,
however, remain clear, allowing a spectacular look at a spring day in
Iceland.

This false-color image uses visible, near-infrared, and short-wave
infrared (MODIS bands 7,2,1) to distinguish snow and ice from cloud. In
this band combination, snow and ice will appear bright electric blue
while cloud typically remains white. However, small ice crystals
carried in high-level clouds will give that type of cloud a light blue
tint, as seen in the high, cold cloud in this image. Vegetation appears
vivid green while water appears inky-blue or black.
