Determination of Local Slope on the Greenland Ice Sheet Using a Multibeam Photon-Counting Lidar in Preparation for the ICESat-2 Mission [PDF]

The greatest changes in elevation in Greenland and Antarctica are happening along the margins of the ice sheets where the surface frequently has significant slopes.

Spaceborne Canopy Height Products Should Be Complemented With Airborne Laser Scanning Data: Toward a European Canopy Height Model

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Measuring and mapping vegetation structure is essential for understanding the functioning of terrestrial ecosystems and for informing environmental policies. Recent years have seen a growing demand for high‐resolution data on vegetation structure, driving their prediction at fine resolutions (1–30 m) at state, continental, and global spatial ...

The Evolving Decline of Landfast Sea Ice in Northern Alaska and Adjacent Waters: Results from an Updated Climatology

Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract We present a new 27‐year record of landfast sea ice extent in northern Alaska and adjacent waters, which uses ice chart data to extend a previous analysis based on synthetic aperture radar (SAR) imagery. This new climatology provides updated information on the decline of landfast ice in a region of the Arctic that has seen extensive losses of ...

Assessing canopy height measurements from ICESat-2 and GEDI orbiting LiDAR across six different biomes with G-LiHT LiDAR

Environmental Research: Ecology
The height of woody plants is a defining characteristic of forest and shrubland ecosystems because height responds to climate, soil and disturbance history.

Observing Waves in Sea Ice With ICESat‐2

Geophysical Research Letters, 2020
AbstractThe coupled interaction of ocean surface waves and sea ice is important in determining the thermodynamic and dynamic properties of sea ice and its relationship to the ocean and atmosphere. Wave‐ice interactions create the marginal ice zone (MIZ), a region critically important for ecology, transportation, and the polar energy budget.

Characterisation and Classification of Resident Space Objects Using Radar Networks

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper describes a simulated environment for generating Inverse Synthetic Aperture Radar (ISAR) images and interferometric point clouds using a three‐receiver radar configuration, along with the creation of extensive datasets to train and evaluate deep learning models under varying Signal‐to‐Noise Ratio (SNR) conditions. Findings show that modified
