Dear Prof. Zhang,

one of the reviewers has additional comments. Could you please address them (see below).
Once you have dealt with them please submit a revised manuscript and a point-to-point response.

Best regards,
Christian Franzke

Here are some questions on the additional numerical experiments shown in Fig. 3 (Box-plot of the PSO, WSA and ACPW methods for TC Fitow at 60 km resolution) of the revised manuscript. In Fig.2, we find large differences among the initial objective function values for the PSO, WSA and ACPW methods, and the one for the ACPW method is even approximately equal to the final objective function value obtained by the PSO method. Does this disparity exists in the numerical experiments shown in Fig. 3? If so, the comparison of the objective function values gained respectively by the PSO, WSA and ACPW methods cannot support the better optimization performance of the ACPW methods. Accordingly, the descending degree of the objective function value for the three methods should be compared.

Dear Dr. Zhang,

I am happy to accept your manuscript for publication in NPG.

Thank you for considering NPG for your publishing your research.

Best regards,
Christian
