Update: Physical Setting- Pollution Comparison

Last Semester, I commented on the relationship between Xi'an's physical setting and its air quality issues. However, I did not post a photo highlighting this phenomena. So, below are two photos taken from a footbridge near my house.



Notice the Qin Ling mountains in the background are visible on a day with good air quality while even some of the foreground buildings fade away on a bad air quality day.
