RCO-Other = residential, commercial, and other sectors.

^a Note: “calculated” emissions depend on meteorological variables and are computed at the time of model simulation. For further details see Appendix B, Supplementary Table 2. CEDS emissions include NH₃, NO_x, SO₂, NMVOCs, BC, and OC but not the mineral component of primary PM₂₅ emissions; the latter are included separately in sectors 14 (AFCID dust) and 15 (windblown dust].

^b Mineral component of primary PM_{2 5} emissions from anthropogenic sources, including ash from solid fuel combustion, emissions from cement and metals production, construction and agricultural emissions, and resuspended road dust.

^c Excludes coal ash emissions.
