I found this article very interesting. It presents a novel approach that uses lidar measurements to perform coarse pollen speciation in the lower troposphere.

The methodology is clearly explained, and the results are convincing. However, there is insufficient discussion of uncertainties. One important point is calibration. Certain aspects need to be clarified for readers so that they can rely on and use this work.

In my opinion, this article is entirely appropriate for ACP and can be published once the additional information requested has been provided. My corrections and questions are in the body of the article (in supplement).

This article provides a new perspective on the use of lidar technology and requires only minor revisions.

The authors in the present study investigated the vertical profiles of pollen grains with a multi-channel elastic-fluorescence lidar and evaluated their findings in relation to the results obtained from real-time devices like Poleno and WIBS as well as to Hirst sampler. In addition, particulate matter originating from the Canadian and German megafires were detected in the atmosphere.

The manuscript is within the aims and scope of ACP. The overall study is well designed and the results clearly presented. The manuscript is well-organized and written. Some typos have been highlighted in the text. Comments regarding specific issues are included in the manuscript.

My recommendation is to be accepted for publication after the authors address all comments.
