Sea ice cover plays a key role in regulating the Earth?s climate by influencing the global atmospheric and oceanic circulation through various feedback mechanisms. The only viable source for the continuous monitoring of sea ice cover, its variability

The Greenland ice sheet (GrIS) is one of the drivers of global sea level rise and plays a crucial role in understanding the global climate changes. Here, we have estimated and analysed the decadal (between 2013–2016 and 2003–2005) and annual (201

Changes in surface elevations of polar ice sheets are the result of changes in ice dynamics and surface mass balance. Here, we present intra- and inter-annual elevation changes over the Antarctic ice sheet using the AltiKa radar altimeter’s 40 Hz g

Ice shelves fringing Antarctica are sensitive indicators of climate change due to the direct interface with the atmosphere and ocean. Meltwater induced by atmospheric warming percolates from the surface into hydrofractures and affects shelf stability
