Particle composition derived from model aerosol species.
| Composition | Fine particle mode (<2.5 μm) | Coarse particle mode (2.5 – 10 μm) |
|---|---|---|
| Sea salt (SEA) | Inferred from Aitken and accumulation mode aerosols species chlorine, sodium, calcium, and magnesium. | Inferred from lumped aerosol species ASEACAT and coarse mode chlorine |
| Ionic particles (ION) | Sum of Aitken and accumulation modes aerosol species sulfate, nitrate and ammonium | Sum of coarse mode aerosol species sulfate, nitrate and ammonium |
| Organic matter (OM) | Sum of 35 aerosol species classified as organic matter | None |
| Black carbon (BC) | Sum of Aitken and accumulation mode of elemental carbon | None |
| Dust | Inferred from aerosol species aluminum, silicon, calcium, iron and titanium [Foroutan et al., 2016] | Inferred from lumped aerosol species ASOIL and coarse mode chlorine |
| Other unspecified particles (UNSPEC) | The difference between the sum of all aerosol species and sum of the five particles listed in this table in Aitken and accumulation modes. | The difference between the sum of all aerosol species and sum of the five particles listed in this table in coarse mode. |
