Archived data from Northern Circumpolar Soil Carbon Database

The Northern Circumpolar Soil Carbon Database (NCSCD) is a geospatial database created for the purpose of quantifying storage of organic carbon in soils of the northern circumpolar permafrost region.

The spatial base of the NCSCD is a polygon database describing soils in the northern circumpolar permafrost regions. The database was compiled by combining and homogenizing several regional/national soil maps. To calculate storage of soil organic carbon, these soil maps have been linked to field-data on soil organic carbon storage from a total of 1,647 sites from around the circumpolar permafrost region.

The NCSCD contains information on fractions of coverage of different soil types (following U.S. Soil Taxonomy nomenclature) as well as storage of soil organic carbon (kg/m2) between 0-30 cm and 0-100 cm depth. The NCSCD is available either as a polygon-based database (which is the original format) or converted to gridded data. Gridded data products are available in different spatial grid resolutions and in formats adapted for use in desktop GIS-applications and model applications.

北方环极土壤碳数据库（Northern Circumpolar Soil Carbon Database，NCSCD）是一个地理空间数据库，旨在量化北方环极多年冻土区土壤中有机碳的储量。

NCSCD的空间基础是一个描述北方环极多年冻土区土壤的多边形数据库。该数据库通过整合并均质化多个区域/国家土壤图编制而成。为计算土壤有机碳储量，这些土壤图已与来自环极多年冻土区共1647个站点的土壤有机碳储量实地数据相关联。

NCSCD包含不同土壤类型的覆盖比例信息（遵循美国土壤分类系统命名法）以及0-30厘米和0-100厘米深度的土壤有机碳储量（千克/平方米）信息。该数据库既可以以多边形数据库形式（原始格式）获取，也可以转换为栅格数据。栅格数据产品提供多种空间网格分辨率，并采用适用于桌面GIS应用和模型应用的格式。
