Surface elevation data for Amery Ice Shelf, derived from ERS satellite radar altimetry
Data gaps over rocks and regions of high topographic relief (edges of Amery) and some data dropouts towards the ice front. Uses ERS altimeter waveform data from the European Space Agency satellite ERS-1 Phases E and F (168 day phases) ERS data were subject to several processing stages:i) Waveform fi...
