Fig. 5From: Comparison of different machine learning approaches for tropospheric profiling based on COSMIC-2 dataFitting results for different months on the Northern (left panels) and Southern (right panels) hemispheres. The bars show vertically averaged RMSE for temperature (a, d), pressure (b, e), and water vapor partial pressure (c, f) computed between ERA5 and different ML models or CDAAC wetPf2 product on test data sets.
