Figure 4. (a) Original (red lines) and homogenized (blue lines) surface air temperature series at urban (solid lines) and rural (dashed lines) stations in Beijing. (b) Urban–rural temperature differences determined by original (red line) and homogenized (blue line) observations, based on the daily temperature data-set in Li and Yan (Citation2010). The urban stations include Beijing, Changping, Fengtai, Mentougou, Tongzhou, Haidian, and Shijingshan. The rural stations include Huairou, Pinggu, and Miyun. More details can be found in Wang et al. (Citation2013a).
