    <dct:description>&lt;p&gt;The dataset consists of a map of above ground forest biomass (AGB, unit: tons/ha i.e., Mg/ha) of the African continent 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.&amp;nbsp;&lt;/p&gt; &lt;p&gt;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., ESSDD, 2020).&amp;nbsp;&lt;/p&gt; &lt;p&gt;In this repository, the AGB data are available in form of tiles of 2&amp;deg; x 2&amp;deg; for the African continent (bounding box:&amp;nbsp;longitude -26&amp;deg;E/+56&amp;deg;E latitude: -36&amp;deg;N/+38&amp;deg;N).&lt;/p&gt; &lt;p&gt;This dataset is the basis for the&amp;nbsp;official GlobBiomass dataset consisting of global estimates of forest biomass with 1 ha pixels (&lt;a href="https://doi.pangaea.de/10.1594/PANGAEA.894711"&gt;https://doi.pangaea.de/10.1594/PANGAEA.894711&lt;/a&gt;). The dataset in this repository represents the original GlobBiomass dataset of AGB for Africa from which the official dataset was obtained after averaging from 25 m to 100 m.&amp;nbsp;Given the lower accuracy of the 25 m pixel-based estimates, it is recommended to use the official GlobBiomass dataset&amp;nbsp;unless detailed spatial resolution is a fundamental asset.&amp;nbsp;&lt;/p&gt; &lt;p&gt;Technical specifications are provided in the file README_GLOBBIOMASS_Africa_20210428.pdf&lt;/p&gt;</dct:description>
