Lidar Aboveground Vegetation Biomass Estimates in Shrublands: Prediction, Uncertainties and Application to Coarser Scales [PDF]

Remote Sensing, 2017
Our study objectives were to model the aboveground biomass in a xeric shrub-steppe landscape with airborne light detection and ranging (Lidar) and explore the uncertainty associated with the models we created. We incorporated vegetation vertical structure information obtained from Lidar with ground-measured biomass data, allowing us to scale shrub ...

Importance of structural and spectral parameters in modelling the aboveground carbon stock of urban vegetation

International Journal of Applied Earth Observation and Geoinformation, 2019
Abstract This study aims to comparatively assess the effectiveness of spectral and structural parameters of vegetation in estimating aboveground carbon (AGC) stock by vegetation type. A total of 38 structural metrics (including 21 percentiles) derived from LiDAR data, and 105 spectral indices and reflectance (including 10 percentiles for each of them)

Carbon stock in aboveground biomass of vegetation at the High Tatra Mts. twelve years after disturbance

Central European Forestry Journal, 2017
The paper focused on the estimation of aboveground biomass and its carbon stock in the vegetation cover on the territory of the High Tatras twelve years after a large-scale wind disturbance. Besides biomass quantification of main plant groups (i.e. trees

Regional contingencies in the relationship between aboveground biomass and litter in the world’s grasslands [PDF]

, 2013
Based on regional-scale studies, aboveground production and litter decomposition are thought to positively covary, because they are driven by shared biotic and climatic factors.

Evaluation of optical and microwave-derived vegetation indices for monitoring aboveground biomass over China

Geo-Spatial Information Science
The microwave-derived vegetation optical depth (VOD) products were used to monitor aboveground biomass (AGB) at regional to global scales, but the ability of VOD to monitor AGB in China is uncertain. This study evaluated the sensitivity of four VOD products (e.g. L-VOD, IB-VOD, LPDR-VOD, and Liu-VOD) and optical vegetation indices (VI) (e.g. NDVI, EVI,
