08 - IDW and TPS correction

Spatial IDW and TPS correction of the hourly radar precipitation values for each centroid of the study area. Once the residuals at the rain gauge locations were calculated with respect to the radar, the error was interpolated exploiting the Inverse Distance Weighting (Thin Plate Spline) method and added to the radar values in each 1 km x 1 km cell (radar considered as the trend). Naming conventions: P_R_idw_n°.csv and P_R_tps_n°.csv for example, P_R_idw_2.csv, number varies based on the centroid which it refers to.
