Changes in tropospheric air quality related to the protection of stratospheric ozone in a changing climate.

ABSTRACT: Ultraviolet (UV) radiation drives the net production of tropospheric ozone (O₃) and a large fraction of particulate matter (PM) including sulfate, nitrate, and secondary organic aerosols. Ground-level O₃ and PM are detrimental to human health, leading to several million premature deaths per year globally, and have adverse effects on plants and the yields of crops. The Montreal Protocol has prevented large increases in UV radiation that would have had major impacts on air quality. Future scenarios in which stratospheric O₃ returns to 1980 values or even exceeds them (the so-called super-recovery) will tend to ameliorate urban ground-level O₃ slightly but worsen it in rural areas. Furthermore, recovery of stratospheric O₃ is expected to
