Photochemical Aging of Organic Aerosols Drives the Enhancement of Carbon-13 Isotope Ratios of Oxalic, Malonic, Glyoxylic Acids and Total Carbon during the Arctic Polar Sunrise

This dataset contains compound-specific stable carbon isotope ratios of LMW dicarboxylic acids in the Arctic Alert aerosols (1991) from late winter to early summer including polar sunrise event. In addition to d13C data of diacids, total carbon (TC) concentrations and d13C (TC) and concentrations of diacids and related compounds are included.
