  • Aerosol-cloud interaction inferred from MODIS satellite data and global aerosol models 
    Myhre, Gunnar; Stordal, Frode; Johnsrud, M; Kaufman, YJ; Rosenfeld, D; Storelvmo, Trude; Kristjansson, Jon Egill; Berntsen, Terje Koren; Myhre, A; Isaksen, Ivar S A (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2007)
    We have used the MODIS satellite data and two global aerosol models to investigate the relationships between aerosol optical depth (AOD) and cloud parameters that may be affected by the aerosol concentration. The relationships ...
  • Modelled radiative forcing of the direct aerosol effect with multi-observation evaluation 
    Myhre, Gunnar; Berglen, Tore Flatlandsmo; Johnsrud, M; Hoyle, Christopher; Berntsen, Terje Koren; Christopher, SA; Fahey, DW; Isaksen, Ivar S A; Jones, TA; Kahn, RA; Loeb, N; Quinn, P; Remer, L; Schwarz, JP; Yttri, KE (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2009)
    A high-resolution global aerosol model (Oslo CTM2) driven by meteorological data and allowing a comparison with a variety of aerosol observations is used to simulate radiative forcing (RF) of the direct aerosol effect. The ...
