Periglacial landscapes, which are defined by the presence of subsurface permafrost and characterized by significant seasonal freeze/thaw cycles, are shaped by diverse geomorphic processes including ice wedging, frost heave, solifluction, and thermokarst, and marked spatiotemporal variation in near surface geophysical characteristics (e.g., soil saturation fraction, ice content, thaw depth). Interferometric synthetic aperture radar (InSAR) is an active remote sensing technique capable of imaging centimetric-scale ground surface displacement at high spatial and temporal resolutions. The InSAR technique has been used to characterize surface subsidence and uplift associated with the seasonal freezing and thawing of the active layer,  secular deformation associated with thermokarst, permafrost degradation, and geomorphologic change. Furthermore, the integration of the InSAR method with complementary geophysical methods can provide unique insights into the near subsurface of periglacial landscapes otherwise not achievable with a single-method modality. Here, we will discuss several illustrative case studies in which InSAR has been used to characterize the near surface in periglacial landscapes, either singularly or with a complementary geophysical method.
