ORNL DAAC: This dataset contains forest vertical structure and associated uncertainty products derived by applying multi-baseline Polarimetric Interferometric Synthetic Aperture Radar (PolInSAR) and Polarimetric Coherence Tomographic SAR (PCT or PC-TomoSAR) techniques. 0000097698 00000 n 0000015090 00000 n These requirements include global coverage of land where biomass (organic matter) exists, nearly full coverage of all land surface properties, sea ice at both poles and mountain glaciers, and frequent coverage of land areas that are deforming rapidly (earthquake faults, volcanic activity, landslide prone areas, etc.). As these new missions host different technologies, each with relative strengths and weaknesses for biomass retrieval, as well as different spatial resolutions, consistently comparing or combining biomass estimates from these new datasets will be challenging. GEDI, ICESat-2 and NISAR will collect useful data for estimating forest biomass. The specific modes assigned to these geographic targets are shown in the combined mode tables below.
