Photo of sky with fog bows over summit station in greenland

A series of fog bows appear over NSF's Mobile Science Facility at Summit Station, Greenland, on July 15, 2012. Fog bows are similar to rainbows but lack brilliant colors because they are caused by smaller liquid water droplets than those in a typical rain cloud. This particular fog bow is caused by a supercooled liquid water cloud near the surface.
