Global mean tropospheric and stratospheric abundance of main short-lived climate forcers

^$Tropospheric (Tropo) and stratospheric (Strat) ozone columns (in Dobson units, DU), aerosol burdens (in Tg) and mean stratospheric water vapour abundance (in ppmv) have been computed considering the chemical tropopause (e.g O₃ < 150 ppbv for Tropo and O₃ ≥ 150 ppbv for Strat). For the case of methane, the total (Tropo+Strat) global burden (in Tg) is shown.

^&The percentage change in the abundance of the different species during each time period has been computed between either AANE or AANE+ANT cases with respect to the NoSLH case.
