Decomposition of the mean squared error and NSE performance criteria: Implications for improving hydrological modelling
TLDR
We present a diagnostically interesting decomposition of NSE (and hence MSE), which facilitates analysis of the relative importance of its different components in the context of hydrological modelling and show how model calibration problems can arise due to interactions among these components.

Toward improved calibration of hydrologic models: Multiple and noncommensurable measures of information
TLDR
This paper suggests that the emergence of a new and more powerful model calibration paradigm must include recognition of the inherent multiobjective nature of the problem and must explicitly recognize the role of model error. Expand
