Dataset for: Discriminatory power of 204Pb-inclusive Pb isotope systematics for seasonal variability in atmospheric Pb: evidence from western Japan

Description: This dataset contains sample information, sampling start and end times, leachate Pb isotope ratios, leachate Pb concentrations, residue Ti concentrations, seasonal classifications, and calculated conventional Pb isotope ratios for coarse-particle aerosol samples collected in Omura, western Japan, from June 2011 to August 2012. The dataset supports the figures, tables, and statistical analyses in the associated manuscript.
