The primary science objective ESA’s Climate Change Initiative Biomass project (Biomass_cci) is to provide global maps of above-ground biomass (Mg ha-1) for multiple epochs (2005/2006, 2010, 2015/6 and annually from 2018 to 2022), with these being capable of supporting quantification of biomass change.

All datasets are available via the CCI Open Data Portal

The CCI BIOMASS project currently delivers spatially explicit estimates of AGB for five epochs and related standard deviations (SDs) as separate map products, plus AGB change on an annual and decadal basis. The AGB product consists of global datasets with estimates of AGB (unit: tons/ha = Mg/ha). 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. The AGB SD product is a separate data layer providing per-pixel SD of the AGB estimates in Mg/ha.

The data products currently provided by the project (year 4, Version 4.0) consist of five maps of AGB and AGB SD based on Earth Observation data acquired in 2010, 2017, 2018, 2019 and 2020, respectively. The spatial resolution of the map products is 100 m. AGB change is expressed as the difference between AGB maps for either two consecutive years (e.g. 2020-2019) or for a decade (2020-2010), together with an estimate of their SD and a quality flag map, which details the reliability of the AGB change estimate.
