Dataset for "A comprehensive characterisation of natural aerosol source samples from expedition ARTofMELT, Arctic Ocean, 2023" by Kojoj et al. (2024)

Data from natural aerosol source characterization experiments carried out during the expedition ARTofMELT (Atmospheric Rivers and the Onset of Arctic Melt) onboard the Swedish icebreaker Oden in the Fram Strait pack ice during the spring transition, 8 May to 14 June of 2023. 65 total samples of snow, ice, lead water and the sea surface microlayer (SML) were collected, melted, atomized, and the resulting aerosol analysed for their microphysical, chemical, and fluorescent properties immediately after collection. The ice nucleating properties and biological cell quantification of the liquid samples was performed after the expedition. This data can be used for characterization and source apportionment of natural Arctic aerosol.
