Ozone, DNA-active UV radiation, and cloud changes for the near-global mean and at high latitudes due to enhanced greenhouse gas concentrations

Changes in total ozone, DNA-active irradiance, and cloud cover averaged at four UV stations in the southern high latitudes (> 55∘ S), based on simulations with increasing and fixed-GHG mixing ratios.
Changes in total ozone, DNA-active irradiance, and cloud cover averaged at four UV stations in the southern high latitudes (> 55∘ S), based on simulations with increasing and fixed-GHG mixing ratios.

We present the future evolution of DNA-active ultraviolet (UV) radiation in view of increasing greenhouse gases (GHGs) and decreasing ozone depleting substances (ODSs). It is shown that DNA-active UV radiation might increase after 2050 between 50° N–50° S due to GHG-induced reductions in clouds and ozone, something that is likely not to happen at high latitudes, where DNA-active UV radiation will continue its downward trend mainly due to stratospheric ozone recovery from the reduction in ODSs.
