The cryosphere consists of frozen water and includes lakes/rivers/sea ice, glaciers, ice
caps/sheets, snow cover, and permafrost. Because highly reflective snow and ice are the …

Abstract The Reference Elevation Model of Antarctica (REMA) is the first continental-scale
digital elevation model (DEM) at a resolution of less than 10 m. REMA is created from …

We present a reference, comprehensive, high-resolution, digital mosaic of ice motion in
Antarctica assembled from multiple satellite interferometric synthetic-aperture radar data …

This study focuses on the present-day surface elevation of the Greenland and Antarctic ice
sheets. Based on 3 years of CryoSat-2 data acquisition we derived new elevation models …

Altimetry is probably one of the most powerful tools for ice sheet observation. Our vision of
the Antarctic ice sheet has been deeply transformed since the launch of the ERS1 satellite in …

Large uncertainties remain in the current and future contribution to sea level rise from
Antarctica. Climate warming may increase snowfall in the continent's interior,,, but enhance …

Digital elevation models (DEMs) of the whole of Antarctica have been derived, previously,
from satellite radar altimetry (SRA) and limited terrestrial data. Near the ice sheet margins …

The unprecedented accuracy of elevations retrieved from the Ice Cloud and Land Elevation
Satellite (ICESat) laser altimeter is investigated and used to characterize the range errors in …

The aim of this work is to assess potential future Antarctic surface mass balance changes,
the underlying mechanisms, and the impact of these changes on global sea level. To this …

Predictions about future changes in the Amundsen Sea sector of the West Antarctic ice sheet
(WAIS) have been hampered by poorly known subglacial topography. Extensive airborne …
