Ozone concentration versus Temperature: Atmospheric aging of soot particles.

open access: yesLangmuir, 2019
The oxidation of soot particles with ozone (O3) increases the particles' ability to act as cloud condensation nuclei (CCN). To asses if this process is a relevant source for CCN in the atmosphere the reaction rate at atmospheric conditions has to be ...
