Applications of SAR Remote Sensing in the Arctic: A Review

We give an overview of some of the applications of Synthetic Aperture Radar (SAR) remote sensing in the Arctic regions. The review places special emphasis on the potential of high resolution SAR to provide quantitative insights - day and night at nearly all-weather conditions - into the physical properties, at meter-scale spatial resolution, of soils (e.g., soil moisture, roughness, and climate-induced permafrost displacements), sea-ice (e.g., ice type, distribution, and motion) and snowpack volumes (e.g., snow cover area, density, and snow water equivalent).
