Increased Ice Thinning over Svalbard measured by ICESat/ICESat-2 Laser Altimetry [PDF]
We used spaceborne laser altimetry data from the ICESat and ICESat-2 missions to obtain ice elevation and mass change rates between 2003-2008 and 2019 over Svalbard. Elevation changes are derived at orbit crossover locations throughout the study area for

Uncertainties on the combined use of ICESat and ICESat-2 observations to monitor lake levels
Lake water level is an important variable to indicate lake hydrological balances and climate change impacts. Benefiting from the launch of the laser altimeters ICESat and ICESat-2, higher spatial-resolution elevation measurements have opened new ...

ICESat-2 for Fluvial Geomorphology
ICESat-2, a space-borne altimeter launched by NASA in 2018, has the ability to resolve the ground at sub-meter resolution. Using novel filtering techniques and data I/O, we are able to visualize bare-ground transects of heavily vegetated terrain.

ICESat laser altimetry over small mountain glaciers [PDF]
Using sparsely glaciated southern Norway as a case study, we assess the potential and limitations of ICESat laser altimetry for analysing regional glacier elevation change in rough mountain terrain.

Estimating Terrain Slope from ICESat-2 Data in Forest Environments
The global digital elevation measurement (DEM) products such as SRTM DEM and GDEM have been widely used for terrain slope retrieval in forests. However, the slope estimation accuracy is generally limited due to the DEMs’ low vertical accuracy over ...

The ICESat-2 Laser Altimetry Mission
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 include dramatic ice loss from ice sheets and rapid declines in Arctic sea ice,

First Assessment of ICESat‐2 Summer Sea Ice Freeboard With Airborne Validation
ICESat‐2 has demonstrated solid performance in retrieving sea ice freeboard during winter, when sea ice surface types are well‐defined and leads provide reliable sea surface height references.
