Tree carbon stock map describes the above ground and below ground carbon on forestry land. The map is based on segmentation of multi-source national forest inventory (MS-NFI) biomass maps. Satellite images are mainly from years 2017 – 2018. Detailed information on MS-NFI-2017 data sources is presented in working paper <https://jukuri.luke.fi/handle/10024/552462> , which also presents coverage areas of different satellite images. Older MS-NFI data was used in cloudy areas. Documentary is provided also in Paikkatietoikkuna <https://kartta.paikkatietoikkuna.fi/> and in Luke’s file service <https://kartta.luke.fi/index-en.html>. MS-NFI data source index map is provided in <https://kartta.luke.fi/>. MS-NFI-2015 data was used in determination of segment boundaries. The values on the map are amount of carbon (10 kg C ha-1). Missing data is 32766 and non-forestry areas and background 32767. Segmented biomass maps were converted to carbon stock map by factor 0.5. More detailed description on the method is presented in the research article. A difference to the description in the paper is that the data is MS-NFI2017 instead of MS-NFI-2015. The data set is produced at Natural Resources Institute Finland (Luke), the study is funded by the Strategic Research Council at the Academy of Finland, Decision no. 312912 (SOMPA) and Horizon Europe (ForestPaths, project no 101056755).
