A primer on forest structure measurement with lidar for ecologists
Ecosphere, Volume 17, Issue 8, August 2026.Abstract Light detection and ranging (lidar) technology has fundamentally advanced the way we measure forest structure, facilitating new insights into ecological processes. Lidar for forest ecology applications is deployed on multiple types of platforms that operate from the ground, air, or space, and each has associated strengths and limitations ...

Statistical Model of Subsurface Scattering Bias in ICESat‐2's ATL06 Product
Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract ICESat‐2 uses visible laser pulses and photon‐counting detectors to range the Earth's surface, providing precision altimetry for measuring ice sheet elevation change. However, since water ice is transparent to visible light, the photon returns recorded by ICESat‐2's ATLAS instrument may originate from subsurface scattering inside the snow or ...

Single-Photon Reflectivity and Depth Imaging by Continuous Measurement of Arrival Time of Photons
IEEE Photonics Journal, 2019 We demonstrate a reflectivity and depth imaging Lidar system based on a novel photon arrival time measurement method. In this method, the arrival time of photons in a scanning position is continuously measured with a common starting point.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract Resonance lidars targeting the D1 ${D}_{1}$ resonance line of potassium at 770 nm have been employed over the past 5 decades to yield numerous insights into the dynamics of the middle and upper atmosphere. It has long been recognized that these measurements can be severely affected by nonlinear behavior in the scattering process, that is ...
