description Grounding line, elevation changes, and melt rates maps of Denman Glacier, East Antarctica. Using satellite radar interferometry from the COSMO-SkyMed mission we map the grounding line of Denman Glacier, East Antarctica. We complement these data with some historical interferometric radar acquisition from the European satellite ERS-1/2. We present new maps of elevation changes on the grounded and floating portions of Denman Glacier obtained by temporally differencing TanDEM-X Digital Elevation Models. ... : To map the grounding line of Denman Glacier, we form SAR interferograms with a one day time interval by coherently combining SAR acquisitions from ERS-1/2 satellites in 1996 and from the Agenzia Spaziale Italiana (ASI) COSMO-SkyMed (CSK) mission between 2016 and 2018. We multi-look each interferogram with a 8x8 averaging window and remove the topographic signal affecting each interferometric acquisition with a TanDEM-X (TDX) at 30 m spacing. We form 29 CSK Differential Interferogram (DInSAR) (i.e. difference between two SAR interferograms) to reveal the vertical motion of ice in response to changes in oceanic tides. We generate a time series of Digital Elevation Model at 12 m spacing and meter-scale vertical precision using SAR bistatic acquisition from the TDX mission. The processing chain includes: a) spaceborne monostatic TerraSAR-X processing; b) bistatic TDX processing; c) interferometric combination of images; d) phase unwrapping; e) phase-to-height conversion; f) geocoding to a latitude/longitude ...
