Interactive comment on “Atmospheric aerosol compositions in China: spatial/temporal variability, chemical signature, regional haze distribution and comparisons with global aerosols” by X. Y. Zhang et al

Zhang et al. investigated the spatial and temporal of aerosol components in China based on long-term measurements in various atmospheric environments, i.e., urban, rural and remote. The chemical composition, seasonal variation, and particle acidity are discussed in detail. In addition, the visibility degradation caused by the increasing anthropogenic emissions in China is systemically investigated as well. Since most of previous studies in China are limited either at a single fixed site or a short-term sampling period, the data presented here is of importance to improve our understanding of the aerosol characteristics over a large scale in China, and also to validate re-
