[0049] 1) Research period: October-December in 2013 and October-December in 2017, the research scope is the central and eastern regions of China (18°-54° north latitude, 92°-136° east longitude).
[0050] 2) Research area division:
[0051] First, the Chinese region (without considering Hong Kong, Macao, and Taiwan) is divided into four major regions: key regions, the Northern Region (NOR), the Southern Region (SOU), the Qinghai-Tibet Plateau region, and the Xinjiang Autonomous Region. The northern region and the southern region are divided according to provincial boundaries; the Qinghai-Tibet Plateau region and the Xinjiang Autonomous Region have small anthropogenic emissions and few measuring stations, so the contribution of emissions from these regions to other regions of China is not considered.
[0052] For the key regions in China that this study focuses on, it is divided into 8 regions, from north to south: R1, the northern part of Beijing-Tianjin-Hebei, including Zhang...
