The image above was captured on March 30, 2014, by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite. The composite image of the eastern hemisphere was compiled from eight orbits of the satellite and ten imaging channels, then stitched together to blend the edges of each satellite pass.

The time-lapse video shows the VIIRS composite for the eastern hemisphere from January 18 to July 25, 2014. Subtle changes in the snow and vegetation cover of the land vie for attention with a dynamic, swirling layer of clouds that are constantly present and constantly moving.
