Short summary

We found that anthropogenic soot, fly ash, and visible organic particles likely adhere to the surface of secondary inorganic particles larger than 200nm due to coagulation. Biomass burning and coal combustion both constantly contribute to anthropogenic particles in the Qinghai-Tibet Plateau (QTP) background atmosphere. Organic coating and soot on the surface of the aged particles could have different impacts on their hygroscopic and optical properties in the QTP compared to the urban aerosols.
