There is no other heavenly body that is as intensely observed as Earth. Alongside the daily cloud formations used for the weather forecast, the “heavenly eyes“ give usup-to-date information about earthquakes, erupting volcanoes, and floods. They monitor the pollution of the Earth’s atmosphere and, with the help of state-of-the-art measurement methods, they can even look deep inside our planet. From his cosmological point of view, the author discovers wholly new facets to our allegedly well-known Earth. This book describes what can be observed from outer space; shows how to measure things, how these insights can be scientifically used; and how these data are then deployed in disaster relief, climate change models, to predict the weather and earthquakes, in aviation, geophysics, etc.\nDirk H.
