Impacts of Spatial Variability on Aboveground Biomass Estimation from L-Band Radar in a Temperate Forest
Estimation of forest aboveground biomass (AGB) has become one of the main challenges of remote sensing science for global observation of carbon storage and changes in the past few decades. We examine the impact of plot size at different spatial resolutions, incidence angles, and polarizations on the forest biomass estimation using L-band polarimetric Synthetic Aperture Radar data acquired by NA...
متن کاملMeasurements of Forest Biomass Change Using L-band Sar Backscatter
Three-year forest above-ground biomass change is to be measured using L-band synthetic aperture radar (SAR) backscatter. Measurements are also made using P-band backscatter for comparison. The radar data were collected in the airborne BioSAR 2007 and BioSAR 2010 campaigns over the hemiboreal Remningstorp test site in southern Sweden. Regression models for biomass will be developed using referen...
متن کاملModeling L-band radar backscatter of Alaskan boreal forest
Synthetic aperture radar (SAR) data were acquired over Bonanza Creek Experimental Forest (Alaska) in March 1988 under thawed and frozen conditions. For h e stands analyzed, Cband backscatter at 4 2 O 4 5 " lacidence angle was 2.7-6.9 dB smaller under frozen than under thawed conditions for white spruce and balsam poplar, with the largest difference at HV and the smallest at EM polarization. The...
متن کاملL-Band SAR Backscatter Related to Forest Cover, Height and Aboveground Biomass at Multiple Spatial Scales across Denmark
Mapping forest aboveground biomass (AGB) using satellite data is an important task, particularly for reporting of carbon stocks and changes under climate change legislation. It is known that AGB can be mapped using synthetic aperture radar (SAR), but relationships between AGB and radar backscatter may be confounded by variations in biophysical forest structure (density, height or cover fraction...
متن کاملEstimation of Tropical Forest Height and Aboveground Biomass from Dual-band InSAR measurements in Peruvian Amazon
In July 2009, Earthdata Inc. acquired Synthetic Aperture Radar (SAR) data over a lager part of the Peruvian lowland Amazon and mountain forests (more than 5000 km 2 ). The project was designed to provide high spatial resolution imagery to the science community to estimate and map forest aboveground biomass and to assess the capability of the measurements for REDD baseline applications. GeoSAR c...
