| Greenhouse gases | Up to 2014, CMIP6 historical values of CO2, CH4, N2O, CFC11 and CFC12 from Meinshausen et al. (2017). From 2015 onwards, greenhouse gas forcings follow the SSP2-4.5 scenario from Meinshausen et al. (2020). |
|---|---|
| Ozone | Radiation scheme sees a seasonally varying but otherwise fixed climatological ozone field. The monthly climatology of ozone concentration is the 1995-2014 average from a preliminary freely-evolving historical CMIP6 run by Michou et al (2020). |
| Tropospheric aerosols | Seasonally-varying tropospheric aerosol concentrations computed as 11-year moving averages from the preliminary freely-evolving run by Michou et al. (2020) using the interactive aerosol scheme TACTIC_v2 scheme. The Michou et al (2020) run has CMIP6 historical forcings up to 2014 and the SSP2-4.5 forcings from 2015 onwards. |
| Volcanic aerosols | Volcanic stratospheric aerosols are the official CMIP6 forcings provided by Thomason et al (2018). |
| Solar forcing | Time-variation of total solar insolation (TSI) is specified from CMIP6 annual mean forcings provided by Matthes et al (2017) |
