Sampling time: 3-4 days per sample for collecting sufficient aerosol loading for the detailed chemical analyses on the filters. 2020-09-30T00:00:00Z After sampling the filters were stored in a freezer and then shipped in thermal insulated boxes to the CNR-ISAC laboratory in Bologna, Italy, where they were kept frozen at about -20º C until extraction and chemical analyses. About half of each filter was used for the off-line characterization by TOC-analyzer, Ion-chromatography and H-NMR (as described in the paper) performed in Bologna. 2021-01-01T00:00:00Z Aliquots of the aerosol extracts were dried under vacuum and re-dissolved in deuterium oxide (D2O) for organic functional group characterization by H-NMR spectroscopy), as described in the present paper and in previous works (i.e., Paglione et al., 2024). The H-NMR spectra were acquired at 600 MHz in a 5 mm tube using a Varian Unity INOVA spectrometer, at the NMR facility of the Department of Industrial Chemistry of the Bologna University. 2022-01-01T00:00:00Z On the basis of the range of frequency shifts, the signals are attributed to H-C containing specific functionalities (Decesari et al., 2000, 2007). Organic hydrogen concentrations directly measured by H-NMR were converted to organic carbon using stoichiometric H/C ratios specifically assigned to functional groups using the same rationale described in previous works (Paglione et al., 2024). The sum of NMR functional group concentrations expressed in C constitutes the total WSOC measured by H-NMR. 2022-01-01T00:00:00Z Some organic tracers were identified in the H-NMR spectra on the basis of their characteristic patterns of resonances and chemical shifts, using for this scope libraries of reference spectra from the literature (of standard single compounds and/or mixtures from laboratory/chamber experiments and/or from ambient field studies at near-source stations). Among such tracers, methane-sulfonic acid (MSA) and low-molecular-weight alkyl amines (namely, di- and tri- methyl amines, DMA and TMA respectively) were quantified, as well as levoglucosan and hydroxy-methane sulfonate (HMSA) This record was created from dataset metadata by ERDDAP Version 2.24
