Measurement of Forest Above-Ground Biomass Using Active and Passive Remote Sensing at Large (Subnational to Global) Scales
2015
Current Forestry Reports
At country to continental scales, remote sensing techniques have been progressively developed to quantify the above-ground biomass (AGB) of these forests, with these based on optical, radar, and/or light ...
Within the global forest area, a diverse range of forest types exist with each supporting varying amounts of biomass and allocations to different plant components. ...
The only method to use globally available remote sensing data was developed by [87] who used passive microwave derived Vegetation Optical Depth (VOD) from the 1990s onwards to retrieve above-ground biomass ...

SMOS retrieval over forests: Exploitation of optical depth and tests of soil moisture estimates
2016
Remote Sensing of Environment
The correlation between the new vegetation optical depth (VOD) product and the height of the forest estimated by ICES at GLAS lidar on a global scale is investigated. ...
Finally, the soil moisture retrieved over forests is investigated, reporting continental maps for Tropical areas and comparisons with ground measurements in selected forests of the US. ...
The retrieval of the optical depth for the boreal region is more complex: the range of forest heights is more limited than in the tropical biome (rarely above 25 m), and there are large climate variations ...
