Full-text available
Random variations of local weather represent the main limiting factor for practical applications of persistent scatterer interferometry (PSI) at the sub-regional level. 190 Sentinel-1 IW SAR scenes taken over European airfields of Vienna, Bratislava, Graz and Longyearbyen, and timely data recorded at airport meteorological stations were used for th...

Full-text available
Three-year-long Sentinel-1-A/B IW SAR time series and timely data recorded at airport meteorological stations were used for the sub-regional analysis of weather-related impacts on the performance of persistent scatterer SAR interferometry (PSI) in European airfields of Longyearbyen, Vienna, Bratislava and Graz. An original correction technique of “...

Meltdown of Ice Bridges and Emergence of New Islands in the Barents-Kara Region Observed by Sentinel-1 INSAR Aleksey Sharov1, Dmitry Nikolskiy2 1JOANNEUM RESEARCH, Austria; 2Sovzond, Russian Federation Natural ice bridges formed by glaciers stretching across water bodies and connecting isolated tracts of land to the mainland belong to relatively un...
Conference Paper
Full-text available
The present investigation was aimed at studying spatial variability and directional dynamics of inland ice/snow fields in relation to lateral variations of surface gravity at the sub-regional scale of tens to hundreds of kilometres. The main goal was to evidence, both theoretically and empirically, the existence and significance of gravitational im...
Conference Paper
Full-text available
ERS, TDX and S1A SAR interferometric models calibrated with ICESat and CryoSat-2 altimetry data were successfully applied to mapping and quantifying recent breakup of the Matusevich Ice Shelf in Severnaya Zemlya. The assessment of the mapped changes showed that the ice shelf lost 123±2.5 km² or two thirds of its area and 9±0.3 km³ of its volume in...
Article
Mass balance of Russia's northernmost ice caps is poorly known and scarcely mapped. Thorough information about glacier fluctuations in the outer periphery of Russian shelf seas is both lacking and highly desired since it may constitute the relevant benchmark for judging and projecting climate change impacts in the entire Arctic. The present study i...
Article
Full-text available
All known glaciological models describing the evolution of Arctic land- and sea-ice masses in changing climate treat the Earth's gravity as horizontally constant, but it isn't. In the High Arctic, the strength of the gravitational field varies considerably across even short distances under the influence of a density gradient, and the magnitude of f...
Article
Full-text available
A combination of satellite interferometry and altimetry was used for generating and upgrading elevation and evolution models of the Northern Glacial Complex in Novaya Zemlya, measuring heights of ice divides and ice coasts, detecting, measuring, interpreting and mapping glacier changes in linear, areal and volumetric terms, and estimating glacier m...
