Unprecedented anthropogenic climate and land use change are dramatically impacting the cold region processes that shape seasonal snowcovers and glaciers worldwide. Billions of people depend on seasonal snowcovers and glaciers to provide essential freshwater flows for local and downstream communities and ecosystems. There are therefore significant incentives to provide better estimates of these changing physical processes through improved observations, analysis, and modelling. These improvements will also benefit geodetic methods that are increasingly used for quantifying large-scale ice-mass change. In this session, we invite contributions on all aspects of snow, ice, and glaciers including impacts on cold-regions meteorology, hydrology, surface-atmosphere-energy exchanges, frozen soil dynamics, glacier dynamics, geodesy, hydrogeology, and groundwater coupling. Contributors are encouraged to share their experiences, insights, and advances in utilizing existing and next-generation tools for observations, analysis, and/or modelling spanning all climate zones. Contributions from diverse and traditionally underrepresented scholars are strongly encouraged to submit abstracts, as are those that span CGU sections.
