Elucidating the present-day chemical composition, seasonality and source regions of climate-relevant aerosols across the Arctic land surface
Moschos, Vaios; Schmale, Julia; Aas, Wenche; Becagli, Silvia; Calzolai, Giulia; Eleftheriadis, Konstantinos; Moffett, Claire E.; Schnelle-Kreis, Jürgen; Severi, Mirko; Sharma, Sangeeta; Skov, Henrik; Vestenius, Mika; Zhang, Wendy; Hakola, Hannele; Hellén, Heidi; Huang, Lin; Jaffrezo, Jean-Luc; Massling, Andreas; Nøjgaard, Jacob Klenø; Petäjä, Tuukka; Popovicheva, Olga; Sheesley, Rebecca J.; Traversi, Rita; Yttri, Karl Espen; Prévôt, André S. H.; Baltensperger, Urs; El Haddad, Imad (Peer reviewed; Journal article, 2022)The Arctic is warming two to three times faster than the global average, and the role of aerosols is not well constrained. Aerosol number concentrations can be very low in remote environments, rendering local cloud radiative ... -

H.; Baltensperger, Urs; El Haddad, Imad (Peer reviewed; Journal article, 2022)Aerosols play an important yet uncertain role in modulating the radiation balance of the sensitive Arctic atmosphere. Organic aerosol is one of the most abundant, yet least understood, fractions of the Arctic aerosol mass. ... -
