Satellite Microwave Radar Observations of Antarctic Sea Ice
Since 1991, the European Space Agency’s two ERS satellites have acquired microwave radar data of Antarctica. ERS data have been recorded by two receiving stations, one German, one Japanese. The former has allowed direct downlink and recording of high bit-rate, high resolution SAR image data of the Weddell and Bellingshausen Seas during station campaigns. The latter has enabled some data from th...
متن کاملAntarctic Ice Sheet and Radar Altimetry: A Review
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 1991. With the launch of ERS2 and Envisat, the series of altimetric observations now provides 19 years of continuous and homogeneous observations that allow monitoring of the shape and volume of ice sheets. Th...
متن کاملSatellite observations of Antarctic sea ice thickness and volume
We utilize satellite laser altimetry data from ICESat combined with passive microwave measurements to analyze basin-wide changes in Antarctic sea ice thickness and volume over a 5 year period from 2003-2008. Sea ice thickness exhibits a small negative trend while area increases in the summer and fall balanced losses in thickness leading to small overall volume changes. Using a five year time-se...
متن کاملArctic sea surface height variability and change from satellite radar altimetry and GRACE, 20032014
Arctic sea surface height (SSH) is poorly observed by radar altimeters due to the poor coverage of the polar oceans provided by conventional altimeter missions and because large areas are perpetually covered by sea ice, requiring specialized data processing. We utilize SSH estimates from both the icecovered and ice-free ocean to present monthly estimates of Arctic Dynamic Ocean Topography (DOT)...
متن کاملIce Measurements by Geosat Radar Altimetry
The surface topography of the Greenland and Antarctic ice sheets is the principal ice parameter obtainable from satellite radar altimetry. The improved ability of the GEOSA T altimeter to follow irregular surfaces and its extended operation have greatly increased the available topographic data on ice sheets for the study of ice dynamics and the possible detection of changes in global ice volume.
