Total ozone content, total cloud cover, and aerosol optical depth in CMIP6: simulations performance and projected changes
International audience This study is focused on the evaluation of the projected changes in total ozone content (TOC), total cloud cover (TCC), and aerosol optical depth at 550 nm (AOD550) over the twenty-first century. For that, we first evaluated current climate (1980–2014) simulations provided by...
