OpenLandMap Soil Water Content at 33kPa (Field Capacity)

  • This dataset provides global soil water content estimations at 33kPa (field capacity) for 6 standard soil depths (0-200cm) at 250m resolution.

  • The data covers the period from 1950 to 2018 and is based on a compilation of various global and regional soil profile databases.

  • Soil water content values are mapped using measured data and spatial prediction models, without relying on Pedo-Transfer Functions (except for bulk density).

  • Users can access and visualize this dataset within Google Earth Engine or through the OpenGeoHub platform.

  • The dataset is available under a CC-BY-SA-4.0 license, requiring attribution for use.

Description

Soil water content (volumetric %) for 33kPa and 1500kPa suctions predicted at 6 standard depths (0, 10, 30, 60, 100 and 200 cm) at 250 m resolution

Training points are based on a global compilation of soil profiles:

Data import steps are available here. Spatial prediction steps are described in detail here. Note: these are actually measured and mapped soil content values; no Pedo-Transfer-Functions have been used (except to fill in the missing NCSS bulk densities). Available water capacity in mm (derived as a difference between field capacity and wilting point multiplied by layer thickness) per layer is available here. Antarctica is not included.
