ACCURACY EVALUATION OF ICESAT-2 ATL08 IN FINLAND

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
Abstract. ATL08 is level-3A land and vegetation height product of ICESat-2 data, which recorded the terrain elevation and surface height parameters at 100 m fixed-length along the ground track. It has been used widely not only in vegetation monitoring at large scale, but also in improving the accuracy of satellite stereo mapping, so, the accuracy of ...

A new Arctic MSS model derived from combined Cryosat-2 and ICESat observations

International Journal of Digital Earth, 2022
Due to the existence of seasonal or perennial sea ice cover, the determination of the Arctic sea surface is more difficult than that of mid-low latitudinal oceans.

A noise removal algorithm based on adaptive elevation difference thresholding for ICESat-2 photon-counting data

International Journal of Applied Earth Observations and Geoinformation, 2023
Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) has shown great potential for near-shore bathymetry. Unavoidably, the photon data acquired has a lot of noise.

Wall‐to‐wall Amazon forest height mapping with Planet NICFI, Aerial LiDAR, and a U‐Net regression model

Remote Sensing in Ecology and Conservation, EarlyView.
Tree canopy height is a key indicator of forest biomass and structure, yet accurate mapping across the Amazon remains challenging. Here, we generated a canopy height map of the Amazon forest at ~4.8 m resolution using Planet NICFI imagery and a deep learning U‐Net model trained with airborne LiDAR data.

Delete---ICESat-2 leaf area index (LAI) Retrieval Comparisons

, 2021
This is the first release of the LAI used for the submitted paper: Guo et al., 2021: Exploring photon-counting laser altimeter ICESat-2 in retrieving LAI and correcting clumping effect. The grid LAI derived from airborne LiDAR data was used to validate the LAI derived from ICESat-2, which has been validated by the field measurements and has the spatial

A Path to Better Science Through Co‐Creation and Open Infrastructure

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Proprietary development solutions are often perceived as being delivered more quickly and easily than open methods, fueling the misconception that they inherently produce better overall outcomes. However, we argue that open development practices can lead to both efficient and maximally impactful outcomes.

Performance Assessment of ICESat-2 Laser Altimeter Data for Water-Level Measurement over Lakes and Reservoirs in China

Remote Sensing, 2020
Although the Advanced Topographic Laser Altimeter System (ATLAS) onboard the Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) was primarily designed for glacier and sea-ice measurement, it can also be applied to monitor lake surface height (LSH ...

A First Look at the Snow/Ice Penetration Effect of SWOT Observations on Water Level of Global Glacial Lakes

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission promises quasi‐global monitoring of glacial lakes, yet the elevation difference arising from its Ka‐band radar penetrating lake snow/ice cover remains unquantified. This poses a challenge to assessing their level changes.
