GlobBiomass dataset of forest biomass, South America N (25 m)

<p>The dataset consists of a map of above ground forest biomass (AGB, unit: tons/ha i.e., Mg/ha) of the South American region (between 10&deg;S and 24&deg;N) for the year 2010 (raster dataset) with a pixel size of 25 m x 25 m. AGB is defined as the mass, expressed as oven-dry weight of the woody parts (stem, bark, branches and twigs) of all living trees excluding stump and roots. Per-pixel estimates of above-ground biomass uncertainty expressed as standard error in Mg/ha (raster dataset) are also provided.&nbsp;</p> <p>The AGB estimates were obtained from spaceborne SAR (ALOS PALSAR, Envisat ASAR), optical (Landsat-7), LiDAR (ICESAT), auxiliary datasets with multiple estimation procedures (Santoro et al., ESSD, 2021).&nbsp;</p> <p>In this repository, the AGB data are available in form of tiles of 2&deg; x 2&deg; (bounding box:&nbsp;longitude -180&deg;E/-26&deg;E latitude: -10&deg;N/+24&deg;N).</p> <p>This dataset is the basis for the&nbsp;official GlobBiomass dataset consisting of global estimates of forest biomass with 1 ha pixels (<a href="https://doi.pangaea.de/10.1594/PANGAEA.894711">https://doi.pangaea.de/10.1594/PANGAEA.894711</a>). The dataset in this repository represents the original GlobBiomass dataset of AGB from which the official dataset was obtained after averaging from 25 m to 100 m.&nbsp;Given the lower accuracy of the 25 m pixel-based estimates, it is recommended to use the official GlobBiomass dataset&nbsp;unless detailed spatial resolution is a fundamental asset.&nbsp;</p> <p>Technical specifications are provided in the file README_GLOBBIOMASS_South_America_N_20210428.pdf</p>
