The CH₄ RFs derived for all the aircraft emission inventories that are present in the model ensemble.^a

Inventories	CH4 RF, mW m−2
	Old	New
AEDT	−6.67	−8.22
AEM	−6.82	−8.41
AERO2K	−7.09	−8.74
REACT4C	−6.97	−8.59
QUANTIFY	−6.96	−8.58
TRADEOFF	−7.11	−8.76

^a Values are those represented in the model ensemble based on MOZART-3 CTM simulations (Old) and recalculated values using a revised simplified expression for the CH₄ RF (New) as presented by Etminan et al. (2016). The NO_x emissions of each inventory are normalized so that all RFs are scaled to the same global total emissions (0.71 Tg(N) yr⁻¹) as in the REACT4C model.
