SAFARI 2000 Derived Soil Properties, 0.5-Deg (ISRIC-WISE)

The World Inventory of Soil Emission Potentials (WISE) database currently contains data for over 4300 soil profiles collected mostly between 1950 and 1995. This database has been used to generate a series of uniform data sets of derived soil properties for each of the 106 soil units considered in the Soil Map of the World (FAO-UNESCO, 1974).

These data sets were then linked to a 1/2 degree longitude by 1/2 degree latitude version of the edited and digital Soil Map of the World (FAO, 1995) to generate GIS raster image files for the following variables: total available water capacity (mm water per 1 m soil depth); soil organic carbon density (kg C/m**2 for 0-30 cm depth range); soil organic carbon density (kg C/m**2 for 0-100 cm depth range); soil carbonate carbon density (kg C/m**2 for 0-100 cm depth range); soil pH (0-30 cm depth range); and soil pH (30-100 cm depth range).
