Tang et al. carried out the Dust-Bioaerosol (DuBi) Campaign over northern China, and investigated the effects of dust events on the amount and diversity of bioaerosols. The results indicate that the number of bacteria showed remarkable increases during the dust events, and the diversity of the bacterial communities also increased significantly, as determined by means of microscopic observations with 4, 6-diamidino-2-phenylindole (DAPI) staining and MiSeq sequencing analysis. In general, this manuscript was well-organized, and the conclusions will help improve the current understanding of bioaerosol dynamics along the transport pathway of Asian dust. This manuscript should be published in ACP.
