Global mass transport processes are increasingly important to measure and understand, and mass variations may be changing with climate change. Both cryospheric change and terrestrial hydrologic processes are important, to different degrees in different climate zones. Global models for cryospheric and hydrologic processes are becoming more mature, but models usually are not yet unified: cryospheric change estimates may not specify where the water goes, and terrestrial hydrological models do not account for cryospheric changes well. The impacts of mass transport are readily measurable using geodesy (e.g., gravity change and Earth deformation), and variations in mass transport may now be a limiting error source on geodetic observables.
This session aims at bringing together researchers from the cryosphere, hydrosphere and geodetic community with the goal of improving geophysical models. We invite contributions incorporating global or regional cryospheric observations and models, as well as efforts that integrate cryospheric change with other terrestrial water storage models. Furthermore, we welcome comparisons of cryospheric or hydrologic models with geodetic observations and studies that aim to disentangle cryospheric and hydrologic signals. We also look for investigations that exploit mutual benefits of improving mass transport modeling and a better understanding of geodetic observables (e.g., implications on geodetic reference frame, and integrative measures like geocenter).
