Long‐term trends in greenness in the alpine zone of northeastern North America from remote sensing

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Alpine zones above treeline in the Appalachian Mountains and adjacent ranges of northeastern North America support distinctive ecological communities that thrive where conditions are too harsh for trees to grow. These communities differ from alpine zones elsewhere on the continent and are a regionally important source of floristic biodiversity,

Airborne lidar observations supporting the ADM-Aeolus mission for global wind profiling [PDF]

, 2012
The Atmospheric Dynamics Mission ADM-Aeolus of ESA will be the first lidar mission to sense the global wind field from space. The instrument is based on a direct-detection Doppler lidar operating at 354.9 nm with two spectrometers for aerosol/cloud ...

Numerical Modelling of Late Pleistocene to Holocene Earthquake‐Induced Progressive Rock Slope Damage in the Paraglacial Serpentine Valley, Prince William Sound, Alaska

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Numerical modelling of earthquake‐induced progressive rock slope damage in the paraglacial Serpentine valley, Prince William Sound, Alaska. Repeated seismicity generates rock mass damage that may have conditioned areas of the slope for failure during present‐day ice retreat.

Least Squares Compactly Supported Radial Basis Function for Digital Terrain Model Interpolation from Airborne Lidar Point Clouds

Remote Sensing, 2018
To overcome the huge volume problem of light detection and ranging (LiDAR) data for the derivation of digital terrain models (DTMs), a least squares compactly supported radial basis function (CSRBF) interpolation method is proposed in this paper.

Geophysical Surveys and LiDAR Topographic Analysis of the Vallum and Its Wider Landscape at Milking Gap, Hadrian's Wall

Geoarchaeology, Volume 41, Issue 5, September/October 2026.
ABSTRACT We present the results of geophysical surveys and LiDAR analysis of the Vallum and wider landscape at Milking Gap, on Hadrian's Wall. Magnetic gradiometry and Electrical Resistivity Tomography (ERT) surveys were utilised to investigate the landscape context of the Vallum and provide insight into the stratigraphy of the preserved earthworks ...

Algorithm for Extracting Digital Terrain Models under Forest Canopy from Airborne LiDAR Data

Remote Sensing, 2014
Extracting digital elevationmodels (DTMs) from LiDAR data under forest canopy is a challenging task. This is because the forest canopy tends to block a portion of the LiDAR pulses from reaching the ground, hence introducing gaps in the data.

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Tracking and modelling native woodland expansion in the Scottish Highlands using LiDAR

Journal of Applied Ecology, Volume 63, Issue 9, September 2026.
Forest restoration projects should utilise the new LiDAR‐based pipelines to effectively map young trees, assess whether targets are met, and plan further action. Notably, the Scottish Government is now commissioning a national airborne LiDAR scan, providing a unique opportunity to upscale our algorithms to create national woodland expansion databases ...
