Using high‐resolution imagery to map Scots pine regeneration in the Scottish uplands
Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.This study utilizes high‐resolution imagery to map over 90,000 naturally regenerating Scots pines across a 3360‐ha area in the Scottish Uplands. Our approach demonstrates that remote sensing can accurately quantify landscape‐scale forest expansion, identifying nearly 85% of saplings over 2 m tall.

Airborne Near Infrared Three-Dimensional Ghost Imaging LiDAR via Sparsity Constraint
Remote Sensing, 2018 Three-dimensional ghost imaging LiDAR via sparsity constraint (3D GISC LiDAR), as a staring imaging method, can obtain both the range information and spatial distribution of a remote target with a single-pixel time-resolved detector.

Lake Tahoe bottom characteristics extracted from SHOALS lidar waveform data and compared to backscatter data from a Multibeam echo sounder [PDF]
, 2002 The waveforms recorded by airborne lidar bathymetry (ALB) systems are currently processed only for depth information. In addition to bathymetry, multibeam echo sounder (MBES) systems provide backscatter data in which regions of different acoustic ...

Leaf Shedding During Drought Reduces Hydraulic Stress in Trees
AGU Advances, Volume 7, Issue 2, April 2026.Abstract Leaf area has long been a proxy for ecosystem function. However, it can be highly variable even in the same forest types across space and time due to variations in local ecohydrology and climatic extremes such as droughts and heatwaves. Leaf shedding in response to drought has been documented at site‐scales, theoretically to avoid hydraulic ...

Defining Scales of Field Studies and Experiments to Assess Marine Cloud Brightening
AGU Advances, Volume 7, Issue 2, April 2026.Abstract Solar radiation modification (SRM) is being discussed as a potential option for addressing climate risks while atmospheric greenhouse gas concentrations are reduced to lower levels. However, understanding of the potential efficacy, impacts, benefits and harms of different SRM approaches remains limited.

Airborne Lidar measurements of the atmospheric pressure profile with tunable Alexandrite lasers [PDF]
, 1986 The first remote measurements of the atmospheric pressure profile made from an airborne platform are described. The measurements utilize a differential absorption lidar and tunable solid state Alexandrite lasers. The pressure measurement technique uses a

Earth and Space Science, Volume 13, Issue 4, April 2026.Abstract On 7–8 January, 2025, the Eaton fire destroyed >9,000 structures and >40 km2 of forest in the northeastern region of the Los Angeles metropolitan area, California. Building damage was primarily assessed through ground investigations, a process that took several weeks due to hazardous conditions and the difficulty of accessing burnt areas. This
