Free-running and nudged versions of a Met Of- 1 Introduction fice chemistry–climate model are evaluated and used to in- vestigate the impact of dynamics versus transport and chem- Previous studies have identified numerous couplings be- istry within the model on the simulated evolution of strato- tween ozone, greenhouse gases, tropospheric ozone pre- spheric ozone. Metrics of the dynamical processes rele- cursors and stratospheric ozone-depleting substances, and vant for simulating stratospheric ozone are calculated, and climate change. Increased carbon dioxide and near-surface the free-running model is found to outperform the previous ozone levels, for TI - The Met Office HadGEM3-ES chemistry–climate model: evaluation of stratospheric dynamics and its impact on ozone JF - Geoscientific Model Development DO - 10.5194/gmd-10-1209-2017 DA - 2017-03-20 UR - https://www.deepdyve.com/lp/unpaywall/the-met-office-hadgem3-es-chemistry-climate-model-evaluation-of-jRq9qrZCFL DP - DeepDyve ER -
