Figure 2. Differences in black carbon aerosol (BCA) transportation to the Arctic for model simulations with three different horizontal resolutions.

(a–f) Mixing ratio of BCA at (a–c) z = 845 m (where z is the height) and (d–f) z = 6250 m averaged over the final 10 days of the simulation, and (g–i) temporal evolution of zonally accumulated column BCA mass concentration simulated at (a,d,g) 3.5-, (b,e,h) 14-, and (c,f,i) 56-km grid resolutions, respectively. The mapping of the figures was created using the Grid Analysis and Display System (GrADS)⁵¹ version 2.1.a1.
