All nine models show a bad agreement between ρ rank and ρ sim rank ; the correlation between uncertainty and error is worse than expected for all models (ρ rank < ρ sim rank ). This is indeed what we would expect based on the error-based calibration plots; the lower-than-one slope for the error-based calibration indicates that the difference between predicted low and high uncertainties is too large. As ρ sim rank is based on the predicted uncertainty distribution, it will return a higher number when the uncertainty distribution is predicted to be wider than what is supported by the errors.
