## The four R scripts are part of the master's thesis by Jonas Hube on the topic: "Abschätzung der Grundwasserneubildung in dem Gebiet der Schwäbischen Alb unter Verwendung von Fernerkundungsdaten" (Estimation of Groundwater Recharge in the Region of the Swabian Alb Using Remote Sensing Data) A more detailed explanation of the background can be found in this thesis. Below is a brief overview of the scripts: ## SoMo.ml_data_prep.R: This script is used to convert the .nc format of the remote sensing data into a .csv format. The global raster data is clipped to the catchment area, which is imported as a shapefile. ## SM_Comparison.R: This script compares two soil moisture time series and evaluates them statistically. ## GWR_Model.R: Here, the soil moisture time series are converted into groundwater recharge time series using the FluSM function. ## Calibration_10_EDs.R: This script calibrates the GWR_Model using the calibration parameters Ks and B. For this, observed groundwater recharge data and a performance metric are required to assess the adjustment of the groundwater recharge. In this work, the weighted Euclidean Distance was used.
