“…15–39 in Supporting Information Table S3). When multiple response variables (e.g., Sediment, TP, TN, NO3-+NO2-) were considered in model calibration, we calculated the overall objective function as the weighted average of individual objective function of respective response variable (Wang & Chen, ).…”

“…that is computed as the weighted average of multiple single-objectives (Wang and Chen, 2012) where m denotes the number of objectives and w i is the weighting factor for the i th (i ¼ 1, 2,y, m) objective (J i ). In this study, the total objective function (J) consists of four single-objectives (that is, m ¼ 4) in terms of four response variables: J 1 for total cumulative respiration (denoted by C-CO 2 ), J 2 for cumulative respired 14 C normalized by added 14 C (denoted by % 14 C-CO 2 ), J 3 for MBC and J 4 for DOC.…”

“…When observations are available for various response variables, the strategy of multi-objective calibration is essential in order to reduce uncertainty in model parameterization (Yapo et al, 1998;Wang and Chen, 2012). We conducted model parameterization aiming at minimizing a synthesized objective function that consists of four objectives in terms of C-CO 2 , % 14 C-CO 2 , DOC and MBC.…”

“…Different from the above single‐point (i.e., medians) analysis, MPSA assesses the parameter sensitivity in the entire parameter space based on the Monte Carlo simulations (Wang et al ., ). The procedure of MPSA is summarized as follows (Wang & Chen, ): (1) Select the parameters and determine their value ranges/distributions. (2) Randomly generate a series of parameter values from certain probability distributions within their ranges.…”
