Digital elevation models for the Lambert Glacier-Amery Ice Shelf system, East Antarctica, from ERS-1 satellite radar altimetry

The Lambert Glacier-Amery Ice Shelf system is a major component of the East Antarctic ice sheet. This paper presents two digital elevation models (DEM s) that have been generated for the Lambert-Amery system from validated Eur opean Remote-sensing Satellite (ERS-1) radar altimeter waveform data. The f irst DEM covers the Amery Ice Shelf only, and was produced using kriging on a 1 km grid. The second is a coarser (5 km) DEM of the entire Lambert-Amer y system, generated via simple averaging procedures. The DEMs provide unpre cedented surface elevation information for the Lambert-Amery system and all ow new insight into the glaciology of the region.
