Functional QTL mapping and genomic prediction of canopy height in wheat measured using a robotic field phenotyping platform. [PDF]
J Exp Bot, 2020 Genetic studies increasingly rely on high-throughput phenotyping, but the resulting longitudinal data pose analytical challenges. We used canopy height data from an automated field phenotyping platform to compare several approaches to scanning for ...

Under-Canopy UAV Laser Scanning Providing Canopy Height and Stem Volume Accurately [PDF]
Forests, 2021 The automation of forest field reference data collection has been an intensive research objective for laser scanning scientists ever since the invention of terrestrial laser scanning more than two decades ago. In this study, we demonstrated that an under-canopy UAV laser scanning system utilizing a rotating laser scanner can alone provide accurate ...

ICESat-2 data classification and estimation of terrain height and canopy height
International Journal of Applied Earth Observation and Geoinformation, 2023 ICESat-2 (Ice, Cloud, and Land Elevation Satellite-2) was launched in 2018 with a photon-counting LiDAR (Light Detection and Ranging) system, ATLAS (Advanced Topographic Laser Altimeter System). It is collecting massive earth elevation data all over the world, which has shown the potential of large-scale forest monitoring.

Large-eddy simulations of surface roughness parameter sensitivity to canopy-structure characteristics [PDF]
Biogeosciences, 2015 Surface roughness parameters, namely the roughness length and displacement height, are an integral input used to model surface fluxes. However, most models assume these parameters to be a fixed property of plant functional type and disregard the ...

Impact of height heterogeneity on canopy turbulence [PDF]
Journal of Fluid Mechanics, 2017 The flow development above and within homogeneous and heterogeneous canopies was experimentally studied using particle image velocimetry in a refractive-index-matching channel. The experiments were designed to gain insight into the effect of height heterogeneity on the structure and spatial distribution of the turbulence.
