Geosynchronous synthetic aperture radar: design and applications [PDF]
Synthetic Aperture Radar (SAR) imaging from geosynchronous orbit has significant potential advantages over conventional low-Earth orbit (LEO) radars, but also challenges to overcome.

Spatially extensive estimates of annual accumulation in the dry snow zone of the Greenland Ice Sheet determined from radar altimetry [PDF]
We present estimates of accumulation rate along a 200 km transect ranging in elevation from 2750 to 3150 m in the dry snow zone on the western slope of the Greenland Ice Sheet.

Using radar altimetry to update a large-scale hydrological model of the Brahmaputra river basin [PDF]
Measurements of river and lake water levels from space-borne radar altimeters (past missions include ERS, Envisat, Jason, Topex) are useful for calibration and validation of large-scale hydrological models in poorly gauged river basins.

Jason-1/Jason-2 metocean comparisons and monitoring [PDF]
The initial tandem phase of the Jason-2 mission is important for the calibration of the entire altimetric system, not just the records of sea surface height.

Since 1991, several altimetry satellites have been launched, each satellite coming with its own, specific, data format. Moreover, high-level data were developed, using yet other formats.

Lake studies from satellite radar altimetry
For more than 10 years, satellite radar altimetry has been a successful technique for monitoring the variation in elevation of continental surface water, such as inland seas, lakes, rivers, and more recently wetland zones. The surface water level is measured within a terrestrial reference frame with a repeatability varying from 10 ...

Getting around Antarctica: new high-resolution mappings of the grounded and freely-floating boundaries of the Antarctic ice sheet created for the International Polar Year [PDF]
The boundary of grounded ice and the location of ice transitioning to a freely floating state are mapped at 15-m resolution around the entire continent of Antarctica.

Dual Frequency Radar Altimetry-Measuring Greenland Firn Properties from Space [PDF]
For the last eight years, the ESA CryoSat-2 Ku-band radar altimeter has been measuring the elevation of the Greenland Ice Sheet. Ku-band enables surface penetration at firn covered areas, which hampers the direct interpretation of surface elevation ...

Inversion of Surface Soil Moisture from Radar Altimetry Backscattering in Semi-Arid Environments
International audienceSurface Soil Moisture (SSM) is a key parameter of water and energy balances in semi-arid areas. SSM is linearly related to the radar backscattering coefficients (σ0) over sand.
