World Sunlight Map

World Sunlight Map

"A world map showing current sunlight and cloud cover"

The site also offers the map in Mercator and Peters projects along with a dawn/dusk view of the earth, current phase of the moon and a short summary of how the whole thing works.

The developer is even gracious enough to allow his compiled imagery to be freely used on 3rd party sites (with very reasonable usage limits).

All in all a very impressive impressive web mapping implementation.
