Antarctic 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 Altimetry and GrAcE Gravimetry for Studies of Annual Water Storage Variations in Bangladesh
Four different data sources have been compared with respect to observations of the annual water storage variations in the region of Bangladesh. Data from satellite altimeters and river gauges estimates the variation in surface water storage in the major rivers of Bangladesh. The GRACE satellites measure the integrated mass change and hence the terrestrial soil moisture variations, which can als...

متن کاملHysteresis in Cenozoic Antarctic ice-sheet variations
A coupled global climate–Antarctic ice sheet model is run for 10 million years across the Eocene–Oligocene boundary ~34 Ma. The model simulates a rapid transition from very little ice to a large continental ice sheet, forced by a gradual decline of atmospheric CO2 and higher-frequency orbital forcing. The structure of the transition is explained in terms of height mass balance feedback (HMBF) i...
متن کاملSeasonal and Interannual Trends in Antarctic Ice Sheet Microwave Data
Time-series microwave satellite observations are used to investigate seasonal and interannual changes in the surface characteristics of the Antarctic ice sheet. Enhanced-resolution Cband ERS-1/2 scatterometer (ESCAT) backscatter and DMSP SSMI brightness temperature images of Antarctica, acquired on a 3-day interval between 1992 and 1997, have been analysed. Both ESCAT and SSMI data show a clear...
