WebFeb 1, 2024 · Gupta et al. (2009) showed that optimizing αNSE underestimates the variability of simulated flows because the optimum NSE is attained when αNSE = r. In view of this, Gupta et al. (2009) and Kling et al. (2012) recommended the Kling-Gupta efficiency (KGE) in order to circumvent the connections between the variation coefficient and bias and ratios.
