We sincerely thank the reviewer for this helpful comment. In response, we have revised the spatial coverage analysis for fixed stations to account for possible overlap between coverage areas. More specifically, we introduced a simplified overlap coefficient to reduce the overestimation of effective coverage and to better reflect spatial redundancy in dense or partially overlapping monitoring configurations. This change can be found in Section 4.1.2 (Spatial Coverage Analysis).

We appreciate the reviewer's valuable feedback on this matter. Following their suggestion, we have updated our spatial coverage analysis for fixed stations to address potential overlap between different coverage areas. We added a basic overlap coefficient that helps minimize the overestimation of actual coverage while better capturing spatial redundancy when monitoring configurations are dense or have partial overlap. You can find this modification in Section 4.1.2, which covers the Spatial Coverage Analysis.
