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.

Usage

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

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
