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.
