Soil data for water balance computation (Africa only)

Download physical soil properties data for Africa that can be used in water balance computation. The values are for a soil depth of 0 to 30 cm. The spatial resolution is 30 arc-seconds (about 1 km2), aggregated from the original 250m resolution.

For other properties see soil_af, soil_af_elements, soil_af_isda.
