Climate Change Initiative Team Creates New Satellite Map of Africa
This is not a natural state, of course; there is always a weather system bubbling up somewhere.
But if you have access to a lot of images acquired over the course of several months, it becomes possible to construct a mosaic.
This one was produced from observations made by the EU's new Sentinel-2a satellite, which is now routinely mapping Planet Earth.
It is a powerful capability. Sensitive across 13 spectral bands (colours) and able to see details as small as 10m across - the spacecraft's camera "carpet maps" the land surface beneath it. Every strip is 290km wide.
