- Improvement of ice loading/unloading histories
- Improvement of Earth rheological models
- Assessment of elastic loading and viscoelastic GIA models using present-day geodetic and climate model data of all types, or paleo-sea level data.
- Assessing the impact of cryospheric deformation on geodetic reference frames and estimates of plate motions, and the differences between the frames of GIA models and the ITRF.
- Assessing impact of lateral variations in Earth rheology on interpretations of geodetic and geological data
- Investigate the impact of reference frame differences (mainly origin) between GIA models and geodetic reference frames
- Stimulate and support the inter-comparison of 1-D and especially 3-D Earth rheological models
- Stimulate and encourage the further development of open source software tools for modeling cryospheric deformation, and promote the inclusion of ice sheet-solid earth interactions in past and future ice sheet model runs.
