Fig. 4: The time development of total ozone RF relative to 1850.
From: Historical total ozone radiative forcing derived from CMIP6 simulations
The total ozone RF are calculated using a radiative kernel on ozone fields for the historical experiment in CMIP6, the input4MIPs data and OsloCTM3 results. Also shown in the figure is the forcing time development calculated by Checa-Garcia et al.21 on the input4MIPs data, the total ozone forcing time series from IPCC AR5 relative to 1850, the total ozone RF range, and the range of ODS-caused ozone RF assessed by IPCC AR5 in 20113 adjusted to 1850 as the base period. Models without tropospheric chemistry are indicated with a triangle. The RF based on time-slice simulations using the OsloCTM3 is indicated by a square. The underlying numbers for this figure are presented in Supplementary Table 2.
