Temperature (a), pressure (b) and water vapor partial pressure (c) RMSE vertical profiles. The errors are obtained on the testing data set from the operational 1DVar CDAAC wetPf2 product (orange lines), ANN (blue lines) and RF (green lines) approaches with bending angle (solid lines) or refractivity (dashed lines) inputs, with respect to the ERA5 targets. The pink lines present the ERA5 standard deviations of particular meteorological parameters
