چکیده
The manuscript presents results from measurements of new particle formation (NPF) in Beijing during Spring and Winter using high time resolution particle sizers. The characteristics of new particle formation at two adjacent sites were compared to assess the impacts of local traffic emissions on NPF. Traffic exhausts might emit primary particles or gas phase precursors that contribute significantly to secondary particle formation and hence traffic emissions play important roles in severe haze formation in megacities such as Beijing in China. While the topic is important in atmospheric chemistry and is of interest to the general readers of this journal, the manuscript in general is yet to be improved and several major issues need to be resolved before the manuscript can be publishable in the journal.

This manuscript presents a field measurement of new particle formation (NPF) events in urban Beijing, China. The deployment of Fast Mobility Particle Sizers (FMPs) is unique and could deliver new insights into NPF, if interpreted properly. Overall, this manuscript describes interesting phenomena that NPF was enhanced in winter at a street site comparing to a close rooftop site, whereas NPF was ...

This manuscript investigates new particle formation (NPF) observed simultaneously at two sites in a polluted urban environment. The analysis is based high-time resolution measurements, which increases the originality of the results. The background for this study (section 1) as well as the used methods (section 2) are very well written. Contrary to this, there are serious problems in how many of...
