Different behaviors of \(\pmb{{q}_{{c}}^{{r}}}\) and \(\pmb{\mathrm{CDI}^{{r}}}\) during the same time period. (a) \(q_{c}^{{r}}\) and \(\mathrm{CDI}^{r}\) as a function of time in Beijing on Oct. 1st, Thursday. (b) \(q_{c}^{{r}}\) and \(\mathrm{CDI}^{r}\) as a function of time in Shenzhen on Oct. 1st, Thursday. Blue lines in (a) and (b) mark the two instants when \(\mathrm{CDI}^{r}\) stays almost the same while \(q_{c}^{{r}} \) changes obviously. (c) \(q_{c}^{{r}}\) and \(\mathrm{CDI}^{r}\) as a function of time in Beijing on Oct. 28th, Wednesday. (d) \(q_{c}^{{r}}\) and \(\mathrm{CDI}^{r}\) as a function of time in Shenzhen on Oct. 28th, Wednesday. Blue lines in (c) and (d) mark the two instants when \(q_{c}^{{r}} \) stays similar, while \(\mathrm{CDI}^{r}\) changes obviously.
