Ocean tides are the main source of high‐frequency variability in the vertical and horizontal
motion of ice sheets near their marine margins. Floating ice shelves, which occupy about …

Alpine lakes on the Tibetan Plateau (TP) are key indicators of climate change and climate
variability. The increasing availability of remote sensing techniques with appropriate …

Abstract The Reference Elevation Model of Antarctica (REMA) is the first continental-scale
digital elevation model (DEM) at a resolution of less than 10 m. REMA is created from …

We combined an ensemble of satellite altimetry, interferometry, and gravimetry data sets
using common geographical regions, time intervals, and models of surface mass balance …

Accurate prediction of global sea-level rise requires that we understand the cause of recent,
widespread and intensifying, glacier acceleration along Antarctic ice-sheet coastal margins …

This study focuses on the present-day surface elevation of the Greenland and Antarctic ice
sheets. Based on 3 years of CryoSat-2 data acquisition we derived new elevation models …

There are an increasing number of digital elevation models (DEMs) available worldwide for
deriving elevation differences over time, including vertical changes on glaciers. Most of …

Satellite and aircraft observations have revealed that remarkable changes in the Earth's
polar ice cover have occurred in the last decade. The impacts of these changes, which …

Since the first estimates of Svalbard-wide glacier mass balance were made in the early
2000s, there has been great progress in remote sensing and modeling of mass balance …

提高稀少甚至无地面控制点的区域网平差精度, 是实现境外和外业测控困难区域高精度测图的
核心问题之一, 也是主要的技术难点. 为了充分利用高分七号激光测高数据与立体影像同步获取 …
