Short summary
Brown carbon (BrC) has significant but poorly constrained effects on climate. In this work, we investigate the effects of the OH radical on optical properties of secondary BrC in a series of smog chamber experiments. At high relative humidity (RH), we find that the evolution of the particles is complex, exhibiting rapid absorption enhancement followed by slow bleaching. At low RH, bleaching does not occur. These results further our understanding of the highly variable evolution of ambient BrC.
