DUAL-POL X-BAND POL-INSAR TIME SERIES OF A GREENLAND OUTLET GLACIER

摘要

This study investigates X-band (TanDEM-X)rnpolarimetric and interferometric SAR (Pol-InSAR) datarnin order to retrieve information about the temporal andrnspatial variations of surface and subsurface parameters ofrnthe Helheim Glacier in south east Greenland. Inrnparticular, it will be indicated that the copolar phaserndifference between HH and VV could be a suitable proxyrnfor snow accumulation, when Pol-InSAR techniques arernused to assess the underlying scattering mechanism. Byrnapplying a two-phase mixing formula, this approachrnshows potential to reveal the temporal and spatial snowrnaccumulation patterns in time series of TanDEM-X data.
