Chemical characterization of Arctic aerosol for investigating the multi-annual profile of anthropogenic and biogenic markers
The present PhD thesis provides a broad information about the chemical characterization of the Arctic aerosol from 2013 to early 2019 collected at Ny Ålesund, Svalbard Island, Norway. The work aims to investigate the inter- and intra-annual variation of several water-soluble compounds in order to u...
