Correlation of secondary organic aerosol with odd oxygen in Mexico City
Open accessAbstract
Photochemically processed urban emissions were characterized at a mountain top location, free from local sources, within the Mexico City Metropolitan Area. Analysis of the Mexico City emission plume demonstrates a strong correlation between secondary organic aerosol and odd oxygen (O 3 + NO 2). The measured oxygenated‐organic aerosol correlates with odd oxygen measurements with an apparent slope of (104–180) μ g m−3 ppmv−1 (STP) and r 2 > 0.9. The dependence of the observed proportionality on the gas‐phase hydrocarbon profile is discussed. The observationally‐based correlation between oxygenated organic aerosol mass and odd oxygen may provide insight into poorly understood secondary organic aerosol production mechanisms by leveraging knowledge of gas‐phase ozone production chemistry. These results suggest that global and regional models may be able to use the observed proportionality to estimate SOA as a co‐product of modeled O 3 production until more complete models of SOA formation become available.

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.
