This dataset comprises estimates of forest above-ground biomass (AGB) for the years between 2005 and 2012 and between 2015 and 2024. Examples of AGB change maps have been created for consecutive years (2020-2019) and for a decadal interval (2020-2010). Additionally provided in this version release are aggregated data products. These aggregated products of the AGB and AGB change data layers are available at coarser resolutions (1, 10, 25 and 50km).A Python tool is newly provided to compute AGB change maps for any pair of AGB maps. The AGB maps are derived from a combination of Earth observation data, depending on the year, from the Copernicus Sentinel-1 mission, Envisatâs ASAR (Advanced Synthetic Aperture Radar) instrument and JAXAâs (Japan Aerospace Exploration Agency) Advanced Land Observing Satellite (ALOS-1 and ALOS-2), along with additional information from Earth observation sources, e.g., extended ICESat-2 observations to calibrate retrieval models. A cost function that preserves the temporal features as expressed in the remote sensing data is applied to limit biases between the 2005-2012 and the 2015-2024 AGB maps.The AGB data products consist of two (2) global layers that include estimates of:1) above ground biomass (AGB, unit: tons/ha i.e., Mg/ha) (raster dataset). This 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 unit area2) per-pixel estimates of above-ground biomass uncertainty expressed as the standard deviation in Mg/ha (raster dataset)An AGB change product consists of three sets of maps: the AGB change defined as the difference between two AGB maps, the standard deviation of the AGB change and a quality flag of the AGB change.Data are provided in both netcdf and geotiff format.This release of the data is version 7. Compared to version 6, version 7 consists of an update of the maps of AGB for the years 2007, 2010, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022 and new AGB maps for 2005, 2006, 2008, 2009, 2011, 2012, 2023 and 2024. The data has been produced as part of the European Space Agency's (ESA's) Climate Change Initiative (CCI) programme by the Biomass CCI team.
