      Leinonen, Ville; Kokkola, Harri; Yli-Juuti, Taina; Mielonen, Tero; Kühn, Thomas; Nieminen, Tuomo; Heikkinen, Simo; Miinalainen, Tuuli; Bergman, Tommi; Carslaw, Ken; Decesari, Stefano; Fiebig, Markus; Hussein, Tareq; Kivekäs, Niku; Krejci, Radovan; Kulmala, Markku; Leskinen, Ari; Massling, Andreas; Mihalopoulos, Nikos; Mulcahy, Jane P.; Noe, Steffen M.; Van Noije, Twan; O'connor, Fiona M.; O'dowd, Colin; Oliviè, Dirk Jan Leo; Pernov, Jakob B.; Petäjä, Tuukka; Seland, Øyvind; Schulz, Michael; Scott, Catherine E.; Skov, Henrik; Swietlicki, Erik; Tuch, Thomas; Wiedensohler, Alfred; Virtanen, Annele; Mikkonen, Santtu (Peer reviewed; Journal article, 2022)
      Despite a large number of studies, out of all drivers of radiative forcing, the effect of aerosols has the largest uncertainty in global climate model radiative forcing estimates. There have been studies of aerosol optical ...

    • Effect of Long-Range Transported Fire Aerosols on Cloud Condensation Nuclei Concentrations and Cloud Properties at High Latitudes 

      Kommula, Snehitha M.; Buchholz, Angela; Gramlich, Yvette; Mielonen, Tero; Hao, L.; Pullinen, Iida; Vettikkat, Lejish; Ylisirniö, A.; Joutsensaari, J.; Schobesberger, Siegfried; Tiitta, P; Leskinen, Ari; Heslin-Rees, Dominic; Haslett, S. L.; Siegel, Karolina; Lunder, Chris Rene; Zieger, Paul; Krejci, Radovan; Romakkaniemi, Sami; Mohr, C.; Virtanen, Annele (Peer reviewed; Journal article, 2024)
      Active vegetation fires in south-eastern (SE) Europe resulted in a notable increase in the number concentration of aerosols and cloud condensation nuclei (CCN) particles at two high latitude locations—the SMEAR IV station ...

    • Impact of Biomass Burning on Arctic Aerosol Composition 

      Gramlich, Yvette; Siegel, Karolina; Haslett, Sophie L.; Cremer, Roxana S.; Lunder, Chris Rene; Kommula, Snehitha M.; Buchholz, Angela; Yttri, Karl Espen; Chen, Gang; Krejci, Radovan; Zieger, Paul; Virtanen, Annele; Riipinen, Ilona; Mohr, Claudia (Peer reviewed; Journal article, 2024)
      Emissions from biomass burning (BB) occurring at midlatitudes can reach the Arctic, where they influence the remote aerosol population. By using measurements of levoglucosan and black carbon, we identify seven BB events ...
