Correction to: Nature https://doi.org/10.1038/s41586-024-08192-4 Published online 4 December 2024

In the version of this article initially published, there was a typographical error in the units shown on the Fig. 3b y axis, where “C* (μg m–3)” originally read “C* (μg cm–3).” In the article, the original text “Saturation vapour pressure C*” has been amended to read “Saturation concentration C*” in the Fig. 3b caption, in the last paragraph of the “Formation of organonitrates” section, and in four places in the now edited “Saturation concentration” Methods subsection. This correction does not influence our results and conclusions. The figure and text have been amended in the HTML and PDF versions of the article. We thank Dr. John Ness for alerting us to the need for this clarification.
