Soil available water capacity in mm derived for 5 standard layers (0-10, 10-30, 30-60, 60-100 and 100-200 cm) at 250 m resolution

Description

Available Water Capacity (in mm) derived by calculating Water Retention Difference (difference between the field capacity and wilting point; see NRCS Soil Survey Laboratory Methods Manual), and then summing up WRD for all standard layers (0–200 cm). Soil water content (volumetric) in percent for 33 kPa and 1500 kPa suctions predicted at 6 standard depths (0, 10, 30, 60, 100 and 200 cm) at 250 m resolution is available here. These estimates ignore depth to bedrock i.e. existence of any impenetrable layer (total available capacity over the whole land mass is likely about 10–15% smaller). Antarctica is not included.

All files internally compressed using "COMPRESS=DEFLATE" creation option in GDAL. File naming convention:

  • sol = theme: soil,
  • available.water.capacity = available water capacity in mm,
  • usda.mm = determination method: Water Retention Difference in mm,
  • m = mean value,
  • 250m = spatial resolution / block support: 250 m,
  • b0..10cm = vertical reference: 0-10 cm layer below surface,
  • 1950..2017 = time reference: period 1950-2017,
  • v0.1 = version number: 0.1,
