Assimilation of Satellite‐Based Forest Biomass, Productivity and Leaf Area Index in a Global Land Model Incorporating Parameter Spatial Variations and Age Effects

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Disturbances profoundly impact forest capacity for sequestering and storing carbon, and the recovery rates after disturbances vary geographically. Many terrestrial carbon models inadequately simulate the effects of forest disturbances on biomass due to their reliance on equilibrium assumptions, the absence of historical disturbance data, as ...

Adaptation and Response in Drylands: A Dryland Research Agenda and Campaign Strategy

Global Change Biology, Volume 32, Issue 7, July 2026.
The Adaptation and Response in Drylands (ARID) campaign was selected by NASA as a scoping study to develop a research agenda for a dryland field campaign. Here, we detail our ARID science research agenda and implementation plan that were developed based on an extensive community engagement effort in over 160 events with over a thousand scientists, land

Evaluation of Single Photon and Waveform LiDAR

Archives of Photogrammetry, Cartography and Remote Sensing, 2019
Abstract In this short paper, the principles of single photon sensitive LiDAR are presented and compared against state-of-the-art full waveform, linear-mode LiDAR. The differences are explained in theory, and data of either technology are evaluated based on the City of Vienna dataset, captured in 2018 with the SPL100 (Leica) and VQ-1560i

Application of Physically-Based Slope Correction for Maximum Forest Canopy Height Estimation Using Waveform Lidar across Different Footprint Sizes and Locations: Tests on LVIS and GLAS

Remote Sensing, 2014
Forest canopy height is an important biophysical variable for quantifying carbon storage in terrestrial ecosystems. Active light detection and ranging (lidar) sensors with discrete-return or waveform lidar have produced reliable measures of forest canopy

Pre-Detection and Pre-Registration Averaging of Full Wave Signals in Airborne LiDAR Bathymetry

Remote Sensing
A well-known technique to enhance the signal to noise ratio (SNR) of repetitive signals is to average them. The coherent parts of the signal add up constructively while the incoherent parts are averaged out.

Waveform Information Accurate Extraction for Massive and Complex Waveform Data of Hyperspectral Lidar

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Hyperspectral lidar (HSL) has high-precision geometric information and high-resolution spectral information, and its advantageous detection capability has been recognized by scientists at home and abroad. However, how to extract massive and complex HSL data effectively and accurately is an important issue in the current development of HSL.
