Creation of ICESat-2 Footprint Level Global Geodetic Control Points Using Crossover Analysis

Remote Sensing
Precise measurements of the Earth’s surface are possible using satellite laser altimetry data, as demonstrated by NASA’s ICEsat-2 mission. Recently, the vertical accuracy of ICESat-2 data has been validated to

Characterizing ICESat‐2 Snow Depths Over the Boreal Forests and Tundra of Alaska in Support of the SnowEx 2023 Campaign

Water Resources Research
Recent studies show that the Ice, Clouds, and Land Elevation Satellite‐2 (ICESat‐2) can achieve decimeter‐level accuracy over forested and mountainous sites in the western United States, as well as over the glaciers of Alaska.

Assessing Vertical Accuracy and Spatial Coverage of ICESat-2 and GEDI Spaceborne Lidar for Creating Global Terrain Models

Remote Sensing
Digital Elevation Models (DEMs) are a necessity for modelling many large-scale environmental processes. In this study, we investigate the potential of data from two spaceborne lidar altimetry missions, ICESat-2 and GEDI—with respect to their vertical ...

Substantial potential of ICESat-2 photon-counting laser altimetry for reconstructing the lake water depth on the Tibetan Plateau

International Journal of Digital Earth
The littoral zone is crucial in the aquatic ecosystem of lakes, and water depth is often insufficient when using the traditional zigzag echo-sounding method.

ICESat‐2 Onboard Flight Receiver Algorithms: On‐Orbit Parameter Updates the Impact on Science Driven Observations

Earth and Space Science
The ICESat‐2 (Ice, Cloud and Land Elevation Satellite‐2) photon‐counting laser altimeter technology required the design and development of very sophisticated onboard algorithms to collect, store and downlink the observations.
