Soil moisture data and R code for the PSA and DFA methods

We are uploading four supplementary files: S1. Volumetric soil moisture at different locations in the root-zone; S2. Volumetric soil moisture at different depths along vegetated/bare slopes; S3. R code for the Power Spectrum analysis method for soil moisture memory character; S4. R code for the DFA (Detrended Fluctuation Analysis) method for soil moisture predictive period.
