The Northern Circumpolar Soil Carbon Database

Gridded GIS data (tiff-files)

The NCSCD is based on polygons from different regional soils maps homogenized to the U.S. Soil Taxonomy. The database contains information on fractions of coverage of different soil taxa as well as storage of soil organic carbon (hg/m2) between 0–300 cm depth. The data is stored as multiple tiff-files (one file per described parameter). There are separate zipped data-folders with: (1) merged circumpolar datasets at different spatial resolutions (grid sizes: 1°, 0.5°, 0.25°, 0.1°, 0.05° and 0.012°) (2) all regions in folders with files projected in the Lambert Azimuthal Equal Area (LAEA) projection and (grid size: 1000 m) (3) all regions in separate tiff-files with geographic latitude/longitude coordinates (WGS84; grid size: 0.012°).
