soil_af_water: Soil data for water balance computation (Africa only)

Description

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.

The data have a CC-BY 4.0 NC license

Usage

soil_af_water(var, depth = "30cm", path, ...)

Value

SpatRaster

Arguments

var: character. Variables name such as "awcpf23" or "pwp". See Details
depth: character. Either "30cm" or "erzd" (the effective rooting zone depth of maize)
path: character. Path for storing the downloaded data. See geodata_path
...: additional arguments passed to download.file
