SE-Greenland calving front, Køge Bugt Phase-1 achievements: First European SAR mapping of ice velocity at margins / basins Demonstrated the potential of Envisat for height change mapping Time series of calving fronts – 20+ major outlet glaciers Phase-2 developments: Seamless SEC 1991-2017 (ERS, Envisat, CS-2, Sentinel-3) 2x icesheet-wide velocity mapping, Sentinel-1, 2014-17 Time series of velocity 1991-present on 7 main glaciers GRACE-derived mass balance as new ECV Antarctica Ice Sheet CCI project - Close coordination with Greenland CCI (joint CRG, joint GRACE RR)
Antarctic ice sheet CCI Start 2015 – Phase II directly (build on Ice_Sheets_CCI – UK lead): - Altimetry elevation changes 1991-present (ERS, Envisat, CryoSat) - Ice velocities from SAR – common software and cloud computing - GRACE mass balance - Grounding Line Locations on major icestreams and ice shelves
