Short summary
We show that in-cloud aqueous processing facilitates the formation of brown carbon (BrC), based on the simultaneous measurements of the light-absorption properties of the cloud residuals, cloud interstitial, and cloud-free particles. While extensive laboratory evidence indicated the formation of BrC in aqueous phase, our study represents the first attempt to show the possibility in real clouds, which would have potential implications in the atmospheric evolution and radiation forcing of BrC.
