Fig. 4: Comparison of the GWP, EGWP and ATR responses for time horizons between 0 and 100 years.

From: Alternative climate metrics to the Global Warming Potential are more suitable for assessing aviation non-CO2 effects

Fig. 4

Shown are the responses from the GWP (solid line), EGWP (dashed line) and rATR (dotted line), which in its relative form is equivalent to the iGTP. The top row shows the total metric value relative to CO2; the bottom row the responses calculated for each species (colours) relative to the total. Three temporal emission profiles are used, for which the fuel usage profiles are shown in the inset plots: a pulse emission (P-) in (a, d); a fleet emission (F-) in (b, e) and a 1% increasing emission (I-) in (c, f). Each response is shown for the Shared Socioeconomic Pathway SSP2-4.5 with margins (shading) for scenarios SSP1 to SSP5, which are used as the background emissions scenarios in AirClim.
