RF (mW m−2) of the perturbations from the replacement by supersonic aircraft (Scenario S5-S4) on the basis of various model results. Calculations are based on the E39/C radiation code. Additionally, a calculation of the RF using the ULAQ radiation code and ULAQ perturbation pattern is used. The calculation of the totals includes the mean values for CH4 for the SLIMCAT model. Abbreviations: Ctr: contrails; BC: Black carbon; Sulph: sulphate aerosol.
