The dataset includes Pan-European maps of timber vol- ume (Vol), above-ground biomass (AGB), and deciduous- coniferous proportion (DCP) with a pixel size of 10 ×10 m for the reference year 2020. In addition, a measure of prediction uncertainty is provided for each pixel. The maps have been created using a combination of a Sentinel-2 mosaic, Coperni- cus layers, and National Forest Inventory (NFI) data. The mapping was done with the k-Nearest Neighbour (kNN, k = 7) approach with harmonized data of species-specific Vol and AGB from 14 NFIs consisting of approximately 151 0 0 0 field plots across Europe. The maps cover 40 European coun- tries, forming a continuous coverage of the western part of the European continent.
