Fig. 2: Arctic amplification factor (AAF) of AER and GHG.
From: Stronger Arctic amplification from anthropogenic aerosols than from greenhouse gases

Annual ensemble mean AAFAER (blue markers) and AAFGHG (red markers) for each model, along with the difference between (yellow markers). Large hexagonal markers denote the multi-model-mean values, and the number of ensemble members in each model is indicated in parentheses of the figure legend.
