Answer: midday

Figure 1. Photochemical smog over Shanghai. Photochemical smog is a type of smog produced when ultraviolet light from the sun reacts with nitrogen oxides in the atmosphere. It is visible as a brown haze, and is most prominent during the morning and afternoon, especially in densely populated, warm cities

Hope this helps :)

Most likely afternoon as that is when the most production will happen.
