ReUse: REgressive Unet for Carbon Storage and Above-Ground Biomass Estimation. [PDF]

J Imaging, 2023
The United Nations Framework Convention on Climate Change (UNFCCC) has recently established the Reducing Emissions from Deforestation and forest Degradation (REDD+) program, which requires countries to report their carbon emissions and sink estimates through national greenhouse gas inventories (NGHGI).

Estimating urban above ground biomass with multi-scale LiDAR. [PDF]

Carbon Balance Manag, 2018
Urban trees have long been valued for providing ecosystem services (mitigation of the "heat island" effect, suppression of air pollution, etc.); more recently the potential of urban forests to store significant above ground biomass (AGB) has also be recognised. However, urban areas pose particular challenges when assessing AGB due to plasticity of tree

Above-ground biomass and structure of 260 African tropical forests. [PDF]

Philos Trans R Soc Lond B Biol Sci, 2013
We report above-ground biomass (AGB), basal area, stem density and wood mass density estimates from 260 sample plots (mean size: 1.2 ha) in intact closed-canopy tropical forests across 12 African countries. Mean AGB is 395.7 Mg dry mass ha −1 (95% CI: 14.3), substantially higher than Amazonian values, with the Congo

Remote Sensing of Above-Ground Biomass [PDF]

Remote Sensing, 2017
Accurate measurement and mapping of biomass is a critical component of carbon stock quantification, climate change impact assessment, suitability and location of bio-energy processing plants, assessing fuel for forest fires, and assessing merchandisable timber.[...]

Remote Sensing of Above Ground Biomass [PDF]

, 2019
Above ground biomass has been listed by the Intergovernmental Panel on Climate Change as one of the five most prominent, visible, and dynamic terrestrial carbon pools. The increased awareness of the impacts of climate change has seen a burgeoning need to consistently assess carbon stocks to combat carbon sequestration.

Interferometric Ground Cancellation for Above Ground Biomass Estimation

IEEE Transactions on Geoscience and Remote Sensing, 2020
A new processing technique, i.e., ground cancellation, which removes the ground signal from a pair of interferometric synthetic aperture radar (SAR) images, is used to emphasize the response from above-ground targets. This technique is of particular interest when studying forest canopies using low-frequency signals able to reach the underlying ground ...

Above‐ground biomass and species richness in a Mediterranean salt marsh [PDF]

Journal of Vegetation Science, 1993
Abstract.Species composition, above‐ground biomass and diversity of herbaceous communities were recorded in 50 sites on the upper salt marsh of the Guadalquivir delta (SW Spain). Through Canonical Correspondence Analysis relationships were shown between plant‐species characteristics abundance and environmental variables.

Estimation of above‐ground biomass of large tropical trees with terrestrial LiDAR [PDF]

Methods in Ecology and Evolution, 2017
Abstract Tropical forest biomass is a crucial component of global carbon emission estimations. However, calibration and validation of such estimates require accurate and effective methods to estimate in situ above‐ground biomass (AGB). Present methods rely on allometric models that are highly uncertain for large tropical trees.

The BIOMASS Level 2 Prototype Processor: Design and Experimental Results of Above-Ground Biomass Estimation [PDF]

Remote Sensing, 2020
BIOMASS is ESA’s seventh Earth Explorer mission, scheduled for launch in 2022. The satellite will be the first P-band SAR sensor in space and will be operated in fully polarimetric interferometric and tomographic modes. The mission aim is to map forest above-ground biomass (AGB), forest height (FH) and severe forest disturbance (FD) globally with a ...

biomass: an r package for estimating above‐ground biomass and its uncertainty in tropical forests [PDF]

Methods in Ecology and Evolution, 2017
Summary Estimating forest above‐ground biomass (AGB), or carbon (AGC), in tropical forests has become a major concern for scientists and stakeholders. However, AGB assessment procedures are not fully standardized and even more importantly, the uncertainty associated with AGB estimates is seldom assessed.
