Sensitivity analysis and comparison of 7 parameters. a Sensitivity analysis with first-order Sobol indices of 7 parameters from 8 time series with respect to time from 0 s to 1800 s with step size of 18 s. b Comparison of average first-order Sobol indices within 7 parameters. The first diagram displays the sorted parameters by decreasing average first-order Sobol indices. In order to detect the sharp drop in the \(\overline{S_{global, i}}\), the logarithms of relative ratios between the former one and the latter one \(r(i-1, i)\) are shown in the second diagram
