Determining the Freshwater Fluxes from Antarctica with Earth Observation Data, Models, and In Situ Measurements: Uncertainties, Knowledge Gaps, and Prospects for New Advances

The workshop identified relevant datasets and gaps in the current understanding of mass budget estimates and freshwater flux processes from the Antarctic ice sheet (AIS). Presentations included process studies and evaluation of atmosphere, ocean, and ice dynamical models. In addition, new approaches were presented using machine learning methods for assessing mass change, enhancing satellite remote sensing data, and developing blended hybrid datasets. Finally, we developed recommendations for future work.
