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 ... -
