Knowing the aboveground biomass (AGB) stock of tropical forests is one of the main requirements to guide programs for reducing emissions from deforestation and forest degradation (REDD+). Traditional 3D products generated with digital aerial photogra

This paper describes the retrieval of 3-dimensional vegetation density profiles from interferometric synthetic aperture radar (InSAR) using physical models. InSAR’s sensitivity to vertical structure is generally regarded as less direct and more dif

Changes in tropical-forest structure and aboveground biomass (AGB) contribute directly to atmospheric changes in CO 2 , which, in turn, bear on global climate. This paper demonstrates the capability of radar-interferometric phase-height time series a

Mapping and monitoring of forest carbon stocks across large areas in the tropics will necessarily rely on remote sensing approaches, which in turn depend on field estimates of biomass for calibration and validation purposes. Here, we used field plot

This paper proposes the correlation of biomass with Fourier transforms of LiDAR and InSAR vegetation density measurements at vertical and horizontal Fourier spatial frequencies, as a means to estimate biomass. It further suggests that each Fourier fr

This paper discusses a new technique for ocean remote sensing based on detecting GNSS signals, i.e. those transmitted from the Global Positioning System (GPS) or GALILEO (in the future), after they are reflected off the ocean surface, to measure sea

This letter reports the sensitivity of X-band interferometric synthetic aperture radar (InSAR) data from the first dual-spacecraft radar interferometer, TanDEM-X, to variations in tropical-forest aboveground biomass (AGB). It also reports the first t
