The Surface Water and Ocean Topography (SWOT) satellite launched in December 2022 with the goals of delivering the first global inventory of Earth's surface water, high-resolution ocean topography, and temporal variability of water bodies. Although SWOT’s primary objectives target terrestrial hydrology and oceanography, its ~78° latitude orbital turnaround enables up to sub-weekly observations, unaffected by clouds, in many critical polar regions. SWOT may, therefore, also make significant contributions to cryospheric science. To capitalize on this potential, a dedicated Cryosphere Working Group was formed from the 2024 Science Team to explore and expand SWOT’s cryospheric applications. The group’s early efforts yielded the first high resolution (HR) tasking over Antarctica, adding to HR acquisitions for other key Arctic regions. SWOT data has already been used to distinguish sea ice from icebergs, classify sea ice features, map the thickness and 3-D structure of sea ice and ice shelf rifts, and detect variability in major ocean currents. SWOT may also provide valuable insights over river ice. However, challenges remain, including errors in elevation corrections, artifacts in the data, and limitations in existing elevation models. Ongoing work is focused on overcoming these issues to make SWOT a powerful new tool for polar science.
