Abstract: Hydroxyl dicarboxylic acids (OHDCA) are ubiquitous in the atmosphere as an important constituent of secondary organic aerosol, yet the formation mechanisms remain unclear. At an urban background site on the coast of South China, we observed notable levels of OHDCA, with the highest concentration of malic acid (a typical OHDCA species) reaching 533 ng m−3. In the coastal air, the correlation between OHDCA and sulfate was better (R2 = 0.48) in the period when the relative humidity was higher and the sulfate size… Show more
