Retrieval of ultraviolet aerosol absorption from radiation measurements in young wildfire plumes

Abstract. Aerosols play an important role for atmospheric radiative transfer in biomass burning (BB) plumes, where they control photochemistry, direct radiative forcing, and radiation-induced atmospheric dynamics. The optical properties of BB aerosol, however, remain poorly const...

Volatile organic compounds and their role in secondary aerosol chemistry in a cold and dark urban environment

Abstract. Wintertime PM2.5 pollution is a longstanding issue in the urban subarctic environment such as Fairbanks, Alaska. While previous studies suggest that aldehydes may serve as precursors of S(IV) species in aerosols, the role of volatile organic compound (VOC) emissions in...
