CG: n CT: Stratospheric ozone protects the earth’s surface from damaging short-wave ultraviolet (UV) radiation. Ozone is produced in the upper stratosphere by short-wave sunlight, which together with chemical reactions dissociates the ozone again to create a dynamic balance between production and loss. Anthropogenic emissions of inert compounds containing chlorine

GC: n CT: Tropospheric ozone is also recognised to be a threat to human health (WHO, 2003; Lim et al., 2012) and have a deleterious impact on vegetation (Fowler et al., 2009), and through plant damage it impedes the uptake of carbon into the biosphere (Sitch et al., 2007) as
