Review of “Observed impacts of aerosol concentration on maritime tropical convection within constrained environments using airborne radiometer, radar, lidar, and dropsondes” by Amiot et al.
Recommendation: accept after revisions
Overall evaluation: This paper investigates links between various observed atmospheric parameters and the moist convection strength with the overall goal to understand aspects of the so-called convection invigoration. In other words, the motivation is to explore links between factors that in theory can affect moist convection and observed convection strength. The observations come from the CAMP2Ex experiment.
First, I have to say that I am not the right person to review this submission. Although I was involved over the last decade in the discussions of the invigoration conundrum (and for that reason I am signing my review), I feel someone with more expertise in atmospheric observations should also be involved. In particular, I feel the observations lack estimates of their uncertainty. Since this is not my area, I am not sure what to suggest. One possible suggestion is to use a spread of the observations near (in space and time) of the convective event. But this aspect can only address the sampling problem, that is, an uncertainty of a single observation. Another important aspect is an accuracy of the observation itself or uncertainty of a retrieval algorithm. I am not capable to assess if that aspect is appropriately addressed in the submission.
Below I discussed two major points concerning this submission, and follow with several specific comments that require authors’ attention.
Specific major comments.
I have two main issues concerning the motivation and interpretation of results. For the motivation, the convective invigoration discussed in the introduction is poorly explained. There are important published studies that discuss and criticize the original convective invigoration proposal of Andreae et al. (2004) and Resenfeld et al. (2008), including my own papers, that should be included in the introduction. The recent review paper by Varble et al. (ACP 2023, https://doi.org/10.5194/acp-23-13791-2023) should definitely be cited for that.
For the interpretation, I strongly object the suggestion in the summary section 5 that the results support the notion of enhanced aerosol concentrations may invigorate convection (e.g., lines 501 and 510). The key problem is that the correlation does not imply causality. Is it possible that higher aerosol concentrations simply occur in conditions supporting stronger convection (e.g., higher CAPE)? The text in lines 512-515 seems to suggest that such a conclusion might be valid. One suggestion would be to explain the correlation versus causality conundrum in the introduction, and then try to use the results to shed some light on the problem.
However, I have to admit that the discussion of the results in sections 3 and 4 are difficult for me to follow. Specifically, I do not see any trends in figs. 3, 6 and 9, just scattered data points. Does that suggest that the overall outcome of the study is inconclusive? Is there a better way to present the results? See 7 below.
