WebAug 2, 2024 · The KGE' is an expression of distance away from the point of ideal model performance in the space described by its three components (correlation, variability bias and mean bias). KGE' = 1 indicates perfect agreement between simulations and observations. KGE' score for a mean flow benchmark is KGE'≈−0.41.
