In the upper atmosphere: Light from the Sun breaks apart oxygen molecules (UV wavelengths of 215nm or shorter). Some of this monatomic oxygen combines with nitrogen molecules, some with oxygen molecules to make ozone, but most with other monatomic oxygen. Some of the nitrogen+oxygen molecules can catch lower energy light (still UV, but more common) and make ozone also.

Scavengers of ozone are water vapor (decays ozone making hydrogen peroxide, blocks the nitrogen+oxygen path of ozone formation), any compound / process that consumes oxygen, and catalysts (such as some chlorine compounds) that convert ozone back to oxygen.
