Annotation	In this study, we present the measurement results of stable carbon isotope ratio (δ13C) performed on a one-year aerosol samples (n = 96, 24h time resolution during Sep. 2013 - Aug. 2014) for dicarboxylic acids (hereafter “diacids”) and related compounds in PM1 at a rural background site National Atmospheric Observatory Košetice (NAOK), Czech Republic, Central Europe. In previous study on the molecular distributions of diacids (Vodička et al., 2023a), we observed a distinct seasonal variation in the composition of diacids in PM1. In winter, approximately 75% of the organic aerosols originated from anthropogenic sources, whereas in summer, over 75% were attributed to biogenic sources. The objective of this study was to investigate whether these differences are reflected in δ13C of diacids.
