Spatio-temporal changes in radar zones and ELA estimation of glaciers in NyÅlesund using Sentinel-1 SAR
A total of 15 glaciers in the Ny-Ålesund region were studied for their glacier radar zones vis-à-vis ELA over the period 2016–2020, using the multi-seasonal SAR data. All the glaciers were comprised of three zones, namely middle percolation/wet snow, lower percolation/wet snow, and clean ice. Using...

A total of 15 glaciers in the Ny-Ålesund region were studied for their glacier radar zones vis-à-vis ELA over the period 2016–2020, using the multi-seasonal SAR data.
