Unspeciated organic emissions from combustion sources and their influence on the secondary organic aerosol budget in the United States
Open accessAbstract
Significance: Secondary organic aerosol (SOA) formed from the atmospheric oxidation of gaseous combustion emissions is an important component of global fine-particle pollution, which influences the Earth’s energy budget and affects human health. However, existing models underpredict the amount of SOA measured in laboratory experiments and in the atmosphere. We analyze smog chamber and emissions data to demonstrate that unspeciated organics in combustion emissions are a major class of SOA precursors. We develop source-specific parameterizations for these emissions using surrogate chemical compounds. We find that unspeciated organics dominate SOA mass formed from combustion emissions in the United States; therefore, unspeciated organics must be included in models to simulate ambient fine particulate matter concentrations.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
