Short summary

We first reported the size-resolved mixing state of oxalate in the cloud droplet residual, the cloud interstitial, and cloud-free particles by single particle mass spectrometry. Individual particle analysis provides unique insight into the formation and evolution of oxalate during in-cloud processing. The data show that in-cloud aqueous reactions dramatically improved the formation of oxalate from organic acids that were strongly associated with the aged biomass burning particles.
