First results from radar profiles collected along the US-ITASE traverse from Taylor Dome to South Pole (2006â•fi2008)
The 2006/07 and 2007/08 US-ITASE traverses from Taylor Dome to South Pole in East Antarctica provided opportunities to survey the subglacial and englacial environments using 3MHz and 200MHz radar. We present first results of these new ground-based radar data. A prominent basal deformation layer indicates different ice-flow regimes for the northern and southern halves of the Byrd Glacier drainag...

متن کاملRadar Backscatter Measurements From RADARSAT S A R Imagery of South Pole Station , Antarctica
Ice Sheet backscatter around South Pole Station was measured from several different azimuthal angles using RADARSAT-1 S A R data. We observed strong azimuthal anisotropy (3-4 dB) between radar look directions across and along the prevailing wind direction. We speculate that the azimuthal variation of backscatter around the South Pole area may be largely attributed to systematically oriented sas...
متن کاملInversion of Surface Temperature Based on MODIS and ASTER Imagery
In this paper, on the basis of summarizing the main algorithms of retrieval of land surface temperature, the principle of temperature retrieval algorithm based on multi-channel data is described and factors affecting the accuracy of retrieval are analyzed. In addition, mixed pixel emissivity is discussed and the relevant estimation method using the results of classification of visible-band imag...
متن کاملGlacier Monitoring from Aster Imagery: Accuracy and Applications
The optical sensor ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) on board the Terra satellite offers new possibilities for worldwide glacier monitoring. In this paper, its capability and accuracy for selected glaciological applications is evaluated. (a) ASTER’s along-track stereo sensor allows for photogrammetric DEM generation. Here, we apply PCI Geomatica Orthoengine ...
