| Session Description | The positions of geodetic stations in the world can now be determined with a precision measured in millimeters, thus the long-term movement of the Earth's surface can be monitored at the level of ~1 mm/year. This has become possible owing to the accuracy of modern space based geodetic methods (such as VLBI, SLR, GNSS, DORIS), which have revolutionized our view of the Earth, enabling us to observe, for instance, plate tectonics in progress, right now as it happens. This session is devoted to the various geoscience investigations undertaken using space geodesy observations at the local, regional, continental and global scales. Geometrical and gravitational inverted quantities such as crustal deformation, tectonic motion, oscillations associated with environmental loading cycles, mean sea level and gravity field variations, etc. are of interest to this session. Contributions from geodynamic studies as well as geodetic network development and deployment supporting Earth science applications, particularly in Asia and Pacific areas, are also welcome to this session. A particular interest to this session is also the impact of analysis strategies as well as technique systematic errors on the inverted quantities and their geophysical interpretation. Novel approaches of data analysis aiming at improving the positioning performance and reference frame determination of the four techniques are also welcome. |
