As part of a large acid-rain research project of China’s National Basic Research Program (‘973 programme), aircraft campaigns were conduced in summer and autumn 2007 in several regions of China to improve the  understanding of vertical  exchange/transport processes and to evaluate satellite retrieval algorithms as well as regional transport. The study regions included the northeast (NE), which is China’s major agricultural base, the northwest (NW), which is sparsely populated and has an arid and semi-arid climate, and the central-eastern (CE) region, which is the largest flat area and thus the most populated and heavily industrialized region of China.

The study was carried out in collaboration with Shandong University, Chinese Research Academy of Environmental Sciences, Institute of Atmospheric Physics of the Chinese Academy of Sciences, and Jilin Weather Modification Office.

The results show:

(1) The important role of the Warm Conveyer Belt in transporting pollution from the North China Plains to the northeast China and regions further downwind during summer (Ding et al., 2009) and

(2) Satellite OMI SO2 retrieval may underestimate the SO2 column in heavily polluted central-eastern region of China (Xue et al., 2010).
