We sincerely thank the reviewer for this helpful comment. In response, we have added a dedicated section discussing the main limitations of the study. More specifically, we now address: • data and methodological limitations, including the use of literature-derived coefficients, simplified scenario assumptions, and the absence of newly collected field data; • technical and measurement limitations, including sensor drift, cross-sensitivity, non-linear sensor behavior, simplified correction assumptions, and omitted engineering factors such as airflow stability, inlet configuration, power supply, and GPS precision; • geographical and temporal limitations, including the fact that the framework was developed specifically for Mohammedia and does not account for seasonal variability, long-term trends, or exceptional events. This change can be found in Section 6.3 (Study Limitations and Applicability), including Sections 6.3.1 to 6.3.3.

We appreciate the reviewer's valuable feedback on this matter. To address their concern, we have included a new section that outlines the key limitations of our study. This section covers three main areas: • Data and methodological constraints, such as our reliance on coefficients from existing literature, the use of simplified scenario assumptions, and the lack of newly gathered field measurements; • Technical and measurement challenges, including issues with sensor drift, cross-sensitivity between different measurements, non-linear responses from sensors, oversimplified correction methods, and missing engineering considerations like airflow stability, inlet design, power supply variations, and GPS accuracy; • Geographic and temporal scope restrictions, particularly noting that our framework was created specifically for Mohammedia and does not incorporate seasonal changes, long-term patterns, or unusual events. These additions appear in Section 6.3 (Study Limitations and Applicability), which includes subsections 6.3.1 through 6.3.3.
