چکیده
Ref2: The following is a review of the manuscript, “The effects of convection on new particle formation in the free troposphere: Case studies” by Benson et al. This review pertains to a revised version of the manuscript. The case studies in this revision are improved and provide a clearer representation of the relationship between air history and new particle formation. However, the discussion of this relationship and implications have not become more clear in this version. A number of statements regarding air mixing, convection, and surface area, and model output are not explained, not clear, or not supported by the current presentation. This manuscript may yet be publishable in ACP provided that the four major and several minor points below are addressed by the authors.

متن کاملThe Effects of Airmass History on New Particle Formation in the Free Troposphere: Case Studies
Recent aircraft studies showed that new particle formation (NPF) is very active in the free troposphere. And, these observations lead to a new question: when does NPF not occur? Here, we provide case studies to show how different meteorological parameters affect NPF in the upper troposphere, using the aerosol size distributions measured at latitudes from 18 N–52 N and altitudes up to 14 km duri...
