Ozone Variation Trends under Different CMIP6 Scenarios

This study compares and analyzes simulations of ozone under different scenarios by three CMIP6 models (IPSL-CM6A, MRI-ESM2 CESM-WACCM). Results indicate that as the social vulnerability anthropogenic radiative forcing is increasing, change total column in tropical stratosphere not linear. Compared to SSP2-4.5 SSP5-8.5 scenarios, SSP1-2.6 SSP3-7.0 are more favorable for increase stratospheric mass tropics. Arctic would never recover scenario; however, Antarctica gradually all scenarios. Under trend mainly determined troposphere. scenario, tropospheric concentration will significantly increase; distinctly middle lower
