List of Chemical Component Species in the MAM7 Aerosol Modes
| Species | Accum. (a1) | Aitken (a2) | Primary carbon (a3) | Fine sea salt (a4) | Coarse sea salt (a6) | Fine dust (a5) | Coarse dust (a7) |

Note. “X” indicates species that are present in both the default and MOSAIC model versions; “O” indicates additional species that are present only in the MOSAIC version. The Na species is bulk primary sea salt in the default model version but is sodium in the MOSAIC version. The Dst species is bulk primary soil dust in the default model version but is other inorganics in the MOSAIC version. (Note that the Liu et al. [2012] MAM7 did not have Dst in the accumulation and Aitken modes.) The last row is number of chemical species in each mode for the default and MOSAIC model versions.
