Short summary

The formation, gas-particle partitioning, and evolution of atmospheric organic peroxides are unclear. We investigated the ozonolysis of α-pinene, and focused on peroxides. We found that gas-particle partitioning coefficients of peroxides are much higher than the values from our theoretical prediction, and some gaseous peroxides undergo rapid heterogeneous decomposition on SOA particles in the presence of water vapor, resulting in the additional production of hydrogen peroxide.
