The updated estimate of soil C storage in the 100–300 cm depth range included in the NCSCDv2 is based on a compilation of pedons from around the circumpolar region. Here you can download summary information about these pedons in spreadsheet format, as a text file and as point shape file.
For detailed technical descriptions of the polygon-data and discussion s regarding use of the database, we refer to this paper published in the journal Earth System Science Data Discussions.
