• Review the state of the art in dual-band altimetry of the cryosphere (Ku, Ka, and Laser)
• Identify the relevant campaign data (in-situ, airborne, and satellite)
• Discuss and summarise processing techniques, algorithms, and limitations for dual-band altimetry of the cryosphere
• Identify gaps in the technical knowledge and observational data, and make recommendations for further studies 

The expected Workshop outputs will be a white paper summarising the state of the art on dual-band altimetry of the cryosphere, to be submitted for peer review, as well as a roadmap for improvement of the scientific readiness level of Ku and Ka algorithms over Ice Sheets and Sea ice.
