Photochemical smog can occur most anywhere. London-type smog comes from factories and the burning of coal and fossil fuels, where photochemical smog comes from hydrocarbons and nitrogen oxides mixing with sunlight.
Mostly in the summer because evryone is out traveling because school is out but smog can happen whenever. sometimes it can occur in every season. It also depends on what state or country you live in for example California is crowded with people so there is a higher chabce for smog to occur.
Ozone layer present in troposphere is known as bad ozone. It is a pollutant and is a major constituent of urabn smog.
Photochemical smog is actually more likely to occur in sunny, warm, and dry conditions. This type of smog forms when pollutants from vehicles and industrial sources react with sunlight, creating harmful compounds like ozone. Rain helps to wash away these pollutants, reducing smog levels.

The layer of atmosphere where weather, clouds, and smog occur is the troposphere. This is the lowest layer of the Earth's atmosphere, extending from the surface up to an average altitude of about 10-15 kilometers. It is where virtually all weather phenomena, including clouds and smog, take place.
The troposphere is the layer of the atmosphere where weather, clouds, and smog occur. It is the lowest layer of the atmosphere and contains approximately 75% of the atmosphere's mass. Weather phenomena like cloud formation, precipitation, and atmospheric mixing primarily occur in the troposphere.
Ozone present in the troposphere is also called as bad ozone. It is also a green house gas. It is the major constituent of the urban smog.
