9. Satellite geophysics. Generelt. C.C.Tscherning, University of Copenhagen, 2013-12-15 9 Some instruments only look ”down” Some instruments may be turned around one axis There is large differences in resolution and coverage. Most are sun-syncroneous Repeat cycle varies a lot: From 1 day (with 5 satellitter)

10. Satellite geophysics. Dephts. C.C.Tscherning, University of Copenhagen, 2013-12-15 10 From sea-surface height minus sea-surface topography (approximately the geoid) gravity may be computed due to the validity of the Laplace equation. Then inverse problem is solved, and dephts are obtained using density of sea-water and a bottom with constant density..

13. Satellite geophysics. SRTM.SRTM C.C.Tscherning, University of Copenhagen, 2013-12-15 13 The Shuttle Radar Topography Mission (SRTM) obtained elevation data on a near- global scale to generate the most complete high-resolution digital topographic database of Earth. SRTM consisted of a specially modified radar system that flew onboard the Space Shuttle Endeavour during an 11-day mission in February of 2000.
