Aboveground biomass mapping by integrating ICESat-2, SENTINEL-1, SENTINEL-2, ALOS2/PALSAR2, and topographic information in Mediterranean forests

GIScience & Remote Sensing, 2022
The Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) provides an extraordinary opportunity to support global large-scale forest carbon mapping, but further research is needed in order to obtain wall-to-wall forest aboveground biomass (AGB) maps with

ICESat-2 for Fluvial Geomorphology

, 2022
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. This presentation was given during the 2022 ESIP January meeting held virtually in January 2022.

Estimating Terrain Slope from ICESat-2 Data in Forest Environments

Remote Sensing, 2020
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 ...

Consolidating ICESat-2 Ocean Wave Characteristics with CryoSat-2 during the CRYO2ICE Campaign

Remote Sensing, 2022
Using the Ice, Cloud, and land Elevation Satellite 2 (ICESat-2) global high-resolution elevation measurements, it is possible to distinguish individual surface ocean waves. With the vast majority of ocean surveying missions using radar satellites, ICESat-

Mass Loss of Greenland and Antarctic Peripheral Glaciers From ICESat and ICESat‐2

Journal of Geophysical Research: Earth Surface
Abstract Greenland and Antarctica's peripheral glaciers are an important but often overlooked element in the global sea‐level rise budget. Here, we use satellite laser altimetry from ICESat and ICESat‐2 to assess the mass loss from Greenland's and Antarctica's peripheral glaciers for three periods: February 2003 ...

Mechanisms of Surface Meltwater Ponding and Drainage on the Greenland Ice Sheet Revealed Using SkySat Imagery and Deep Learning

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surface meltwater impacts Greenland Ice Sheet mass balance indirectly by reducing albedo and promoting hydrofracture. However, fully understanding both processes requires accurate mapping of small‐scale features such as ponds, channels, and moulins that govern meltwater formation and drainage. Here we investigate surface water dynamics at high
