Earth Observation Satellites

eumetsat.jpg

A large number of satellites is used today to explore the earth's atmosphere, the oceans, the earth's structure and the biosphere. Satellites employ a large variety of instruments and techniques from remote sensing and inverse problems to monitor and visualize physical, chemical and biological processes taking place above, in or on the surface of our planet earth.

An alternative (not complete) List of Earth Observation Satellites can be found at List of Earth Observing Satellites. Also, the world meteorological organization is collecting material, see WMO OSCAR. The big satellite missions are run for example by

For political activites see also: Group on Earth Observation, which is trying to build the “Global Earth Observation System of Systems” (GEOSS) from 2005 to 2015.

Here, we link important satellites and satellite programs. Currently, this is a selection only.
