Height-diameter allometry of tropical forest trees [PDF]

open access: yes, 2010
Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry.

Forest structure dependency analysis of L-band SAR backscatter [PDF]

open access: yesPeerJ, 2020
Forest structure plays an important role in forest biomass inversion using synthetic aperture radar (SAR) backscatter. Synthetic aperture radar (SAR) sensors with long-wavelength have the potentiality to provide reliable and timely forest biomass ...

Mapping forest canopy height globally with spaceborne lidar [PDF]

open access: yesJournal of Geophysical Research, 2011
[1] Data from spaceborne light detection and ranging (lidar) opens the possibility to map forest vertical structure globally. We present a wall-to-wall, global map of canopy height at 1-km spatial resolution, using 2005 data from the Geoscience Laser Altimeter System (GLAS) aboard ICESat (Ice, Cloud, and land Elevation Satellite).

Vegetation height products between 60° S and 60° N from ICESat GLAS data. [PDF]

open access: yes, 2012
We present new coarse resolution (0.5 ×0.5 )vegetation height and vegetation-cover fraction data sets between 60 S and 60 N for use in climate models and ecological models.

Quantifying Dynamics in Tropical Peat Swamp Forest Biomass with Multi- Temporal LiDAR Datasets [PDF]

open access: yes, 2013
Tropical peat swamp forests in Indonesia store huge amounts of carbon and are responsible for enormous carbon emissions every year due to forest degradation and deforestation.

New global map of forest canopy height [PDF]

open access: yesEos, Transactions American Geophysical Union, 2012
Just how tall are forests around the world? A new global map shows forest canopy height at 1‐kilometer spatial resolution. Simard et al. used satellite data from the Geoscience Laser Altimeter System aboard the Ice, Cloud, and land Elevation Satellite (ICESat) to create a global map of the height of the forest canopy.

Change detection of mountain birch using multi-temporal ALS point clouds [PDF]

open access: yes, 2013
The use of multi-temporal laser scanner data is potentially an efficient method for monitoring of vegetation changes, for example, at the alpine treeline.

Estimating Forest Canopy Height Using MODIS BRDF Data Emphasizing Typical-Angle Reflectances

open access: yesRemote Sensing, 2019
Forest-canopy height is an important parameter for the estimation of forest biomass and terrestrial carbon flux and climate-change research at regional and global scales.

Estimation of 3D vegetation structure from waveform and discrete return airborne laser scanning data [PDF]

open access: yes, 2012
This study presents and compares new methods to describe the 3D canopy structure with Airborne Laser Scanning (ALS) waveform data as well as ALS point data.

Correcting Underestimation and Overestimation in PolInSAR Forest Canopy Height Estimation Using Microwave Penetration Depth [PDF]

open access: yes, 2022
PolInSAR is an active remote sensing technique that is widely used for forest canopy height estimation, with the random volume over ground (RVoG) model being the most classic and effective forest canopy height inversion approach.
