As a global south researcher, I think this article touches on some critical points within the broader atmospheric science community. My comment for minor revision stems from the author's title, "Strengthening Research in the Global South: Atmospheric Science Opportunities in South America and Africa". For me, there is a strong argument that this should include some examples of collaboration within climatology and meteorology, instead, there is a significant focus on chemistry (justifiably so within the context of the journal).

A second valuable analysis would be to see the number of papers from the WoS results (table 1) that:

1. Was, first authored by a "local" researchers/institution,
2. was written by a team compromised fully of local researchers vs international collaboration and,
3. funded by an international partner vs a local partner.

This could subsequently be visualised in a simple graph, which has a visual impact.

Other than these minor revisions, I believe the paper is valuable and insightful, and this conversation should continue in the community.

Summary

The authors presented Africa and South America as the two geographical areas in the Global South that are underrepresented in the atmospheric science community. The article identified some common challenges and constraints hindering the development of atmospheric science research in the regions. They also highlighted the strengths of the researchers in the regions and their   critical role in the future of atmospheric science research
