    • Measurements of aerosol charging states in Helsinki, Finland 

      Kulmala, M.; Laakso, L.; Vana, M.; Gagné, S.; Leppä, J.; Petäjä, T.; McGrath, M.J; Kerminen, V.-M. (Copernicus Publications, 2011)
      The charging state of aerosol populations was measured with an Ion-DMPS in Helsinki, Finland between December 2008 and February 2010. Based on the charging states, we calculated the ion-induced nucleation fraction to be ...
