Simultaneous organic aerosol characterization and source apportionment at two Antarctic sites (Signy and Halley stations) during Antarctic summer 2018-19 Marco Paglione https://doi.org/10.5281/zenodo.10663786
Short summary
Applying factor analysis techniques to H-NMR spectra, we present the organic aerosol (OA) source apportionment of PM1 samples collected in parallel at two Antarctic stations, namely Signy and Halley, allowing investigation of aerosol–climate interactions in an unperturbed atmosphere. Our results show remarkable differences between pelagic (open-ocean) and sympagic (sea-ice-influenced) air masses and indicate that various sources and processes are controlling Antarctic aerosols.
