Biomass CCI AGB 2017 Dec-2019 | This dataset comprises estimates of forest above-ground biomass for the year 2017. 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.
The data was derived from input data from the PALSAR-2 instrument on the ALOS-2 satellite, and data from the Sentinel-1 satellite. The ALOS-2 PALSAR-2 dataset was obtained from the Japanese Aerospace Exploration Agency (JAXA) in the form of a mosaic of images acquired in 2017. The Sentinel-1 dataset consisted of individual data takes by the 1A and 1B units during 2017 and provided by the European Space Agency.
