ISRIC-WISE global dataset of derived soil properties on a 0.5 by 0.5 degree grid (ver. 3.0)

• This dataset was derived from version 2.0 of the WISE database, holding some 9600 soil profiles, linked to a 0.5 by 0.5 degree raster version of the FAO Soil Map of the World
   
• It includes:
  • soil parameter estimates for the component soil units of each terrestrial grid cell, in un-binned format, and
  • soil parameter estimates aggregated or binned into a number of predefined classes. 
     
• Parameter estimates are presented for the topsoil (0-30 cm) and the subsoil (30-100 cm) for: content of organic carbon, total nitrogen, the C/N ratio, pH(H2O), CECsoil, CECclay, base saturation, total exchangeable bases, aluminium saturation, exchangeable sodium percentage (ESP), electrical conductivity of saturated paste (ECe), calcium carbonate content, gypsum content, content of sand, silt and clay, volume of fragments > 2 mm, bulk density, total porosity.
  Total available water capacity (TAWC; -10 to -1500 kPa, corrected for the presence of coarse fragments) is given in mm to 100 cm depth for deep soil units, to 10 cm for shallow Lithosols, and to 30 cm for Rankers and Rendzinas.
  Soil drainage class and 'effective' soil depth are presented on a profile basis.  
    
• The parameter estimates — medians — presented here should be seen as best 'estimates'; possible types and sources of uncertainty are discussed in the documentation.
   
• The GIS project file includes several binned data sets, as examples. These classified data consider the full map unit composition.
