In TeraClimate their soil water content per month at 4x4km
https://www.nature.com/articles/sdata2017191.pdf
They use a one-dimensional Water budget model modified from https://onlinelibrary.wiley.com/action/downloadSupplement?doi=10.1111%2Fgcb.12026&file=gcb12026-sup-0001-AppendixA.doc
But they don't provide soil water capacity on soil water content in mm.
Thy used extractable soil water capacity data at 0.5° from https://hess.copernicus.org/articles/20/1459/2016/hess-20-1459-2016.pdf In this data the Root zone storage capacity is inversely estimated from remote sensing data of evapotranspiration from MODIS and Precipitation data. see sr_cru_2yrs.asc
Should we recompute this by interpolation as they did ? or simply compute the maximum of the time series?
Then this need to be converted in soil volumetric content

soil grid provide clay and sand percentage at global scale at 250 x 250m scale.
https://www.isric.org/explore/soilgrids this can be used to compute
from climatenfi.
But in Marta paper how soil depth is affecting the soil water potential ?
from climatenfi.
An alternative to Campbell equation to compute soil potential (as used in Benito Garzon et al. 2017 GEB ) is the van Genuchten model (as used in SurEau)
See Tuller, M., & Or, D. (2005). WATER RETENTION AND CHARACTERISTIC CURVE. In Encyclopedia of Soils in the Environment (pp. 278–289). Elsevier. https://doi.org/10.1016/B0-12-348530-4/00376-3
for a review of models
from climatenfi.
TerraClimate provide water content in mm but pedotransfer function use SWC in % of volume. The ERA Interim Marta used is in % of volume. So if use percentage of soil water content max (mm/mm) this doesn’t work.
