This POSTER session provides a platform for discussing diverse scientific targets of GGOS with large dynamic ranges in space and time and geodetic infrastructure to enable stable production of accurate data.

This is a POSTER session. The quantification of many geophysical phenomena, e.g. sea level variation, co-and post-seismic deformation, glacial isostatic adjustment, loading effects, but also precise orbit determination of artificial satellites, rely on the availability of a global terrestrial reference frame, such as the ITRF.
