GeoSphere montage. Six images of the whole Earth, with the foreground image centred on Africa. Colours in land areas show natural tones, with sea colours giving an impression of water temperatures (light blue = cool, dark blue = warm). This is a composite of thousands of images made by the NOAA series of weather satellites. Each image was selected for lack of cloud cover and the representation of the surface colours. Selected images were then merged using a graphics supercomputer which allows any view of the planet. These spheres are orthographic projections.
