Radar altimetry has been used to monitor sea level changes and ice sheet elevation
changes for decades. Over mountain glaciers, radar altimetry has limited applications due to …

冰盖的数字高程模型(digital elevation model, DEM) 是对冰盖形状的刻画,
是研究南极冰盖必不可少的基础数据[1]. 然而, 受气候变化影响, 西南极冰盖发生了剧烈的消融 …

The Greenland Ice Sheet contributed 10.6 mm to global sea level rise between 1992 and
2018 and is projected to be the largest glacial contributor to sea level rise by 2100. Here, we …

Satellite radar altimetry has been an important tool for cryospheric applications such as
measuring ice-sheet height or assessing anomalies in snow and ice properties (eg the …

The Greenland Ice Sheet has steadily lost mass over the past decades, presently
representing the second-largest single contributor to global sea-level rise. Even the glaciers …

The Northeast Greenland Ice Stream (NEGIS), the largest basin in Greenland, is undergoing
rapid and sustained dynamic change. However, the ice-flow behaviours over decadal …

Satellite observations are essential for monitoring changes in vast inaccessible polar
regions. CRISTAL is the next polar altimetry mission being developed by the European …

Ice-shelf thickness changes are of critical importance for understanding the stability of the
Antarctic ice-sheet because they restrain the seaward flow of grounded glaciers. In this …

The waveform retracking algorithm is a key factor that affects the accuracy of elevation
change from satellite altimetry over an ice sheet. The elevation change results from four …

Over the last two decades, a small group of researchers repeatedly crossed the Greenland
interior skiing along a 700-km long route from east to west, acquiring precise GNSS …
