ICESat observationsof Arctic sea ice : a first look
Analysis of near-coincident ICESat and RADARSAT imagery shows that the retrieved elevations from the laser altimeter are sensitive to new openings (containing thin ice or open water) in the sea ice cover as well as to surface relief of old and first-year ice. The precision of the elevation estimates...

Summary: | Analysis of near-coincident ICESat and RADARSAT imagery shows that the retrieved elevations from the laser altimeter are sensitive to new openings (containing thin ice or open water) in the sea ice cover as well as to surface relief of old and first-year ice. The precision of the elevation estimates, measured over relatively flat sea ice, is ~2 cm. . Overall, these ICESat measurements provide an unprecedent4ed view of the Arctic Ocean ice cover at length scales at and above the spatial dimension of the altimeter footprint of ~70 m. NASA/JPL |
