What can we learn about the Earth in the invisible light

What we see is not always what there is to be seen. Our visual senses are adjusted only to the visible light which comes from the Sun, but there is wide spectrum of invisible radiation which also provides plentiful of information about the physical world. These invisible wave-lengths are captured by special instruments called multispectral scanners, which may be airborne, or spaceborne. Taking a 'picture' with such a scanner is very much different from taking a snapshot with a hand-held camera, but provides a 'window' into the invisible face of the Earth. Satellite images taken from the distance of hundreds to thousands of kilometres from the surface of the Earth, show a wide range of valuable scientific data on the composition of our planet, it's flora and cultural development. Thus, these beautiful images are not just decorative pictures, but an archive which needs a trained interpreter to be read. Many artificial satellites today monitor the Earth, and their images serve as documents of the changes on local, regional as well as on the global scale. False-colour composite images are designed so to gain as many data on the face of the Earth as possible, and each interpreter can generate composite images by combining images taken in individual wave-lengths, so-called bands or 'channels'. The colours of these composite images are not natural, but computer-generated, and are usually called 'false'. However, not all wave-lengths of the incident radiation are reflected back to the Space to be captured by a satellite camera ; some wave-lengths are being absorbed by water on the surface and in the atmosphere, some are dispersed by reflection on the atmospheric dust, and some is absorbed by the atmosphere. For these reasons, a multispectral scanner is designed to take advantage of atmospheric 'windows' which represent parts of the electromagnetic radiation spectrum which are not absorbed or filtered in the atmosphere.
