  • A production-tagged aerosol module for earth system models, OsloAero5.3-extensions and updates for CAM5.3-Oslo 
    Kirkevåg, Alf; Grini, Alf; Oliviè, Dirk Jan Leo; Seland, Øyvind; Alterskjær, Kari; Hummel, Matthias; Karset, Inger Helene H.; Lewinschal, Anna; Liu, Xiaohong; Makkonen, Risto; Bethke, Ingo; Griesfeller, Jan; Schulz, Michael; Iversen, Trond (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We document model updates and present and discuss modeling and validation results from a further developed production-tagged aerosol module, OsloAero5.3, for use in Earth system models. The aerosol module has in this study ...
  • Aerosol absorption in global models from AeroCom phase III 
    Sand, Maria; Samset, Bjørn Hallvard; Myhre, Gunnar; Gliss, Jonas; Bauer, Susanne E.; Bian, Huisheng; Chin, Mian; Checa-Garcia, Ramiro; Ginoux, Paul; Kipling, Zak; Kirkevåg, Alf; Kokkola, Harri; Le Sager, Philippe; Lund, Marianne Tronstad; Matsui, Hitoshi; Van Noije, Twan; Oliviè, Dirk Jan Leo; Rémy, Samuel; Schulz, Michael; Stier, Philip; Stjern, Camilla Weum; Takemura, Toshihiko; Tsigaridis, Kostas; Tsyro, Svetlana; Watson-Parris, Duncan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Aerosol-induced absorption of shortwave radiation can modify the climate through local atmospheric heating, which affects lapse rates, precipitation, and cloud formation. Presently, the total amount of aerosol absorption ...
  • Arctic amplification under global warming of 1.5 and 2 °C in NorESM1-Happi 
    Graff, Lise Seland; Iversen, Trond; Bethke, Ingo; Debernard, Jens Boldingh; Seland, Øyvind; Bentsen, Mats; Kirkevåg, Alf; Li, Camille; Oliviè, Dirk Jan Leo (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Differences between a 1.5 and 2.0 ∘C warmer climate than 1850 pre-industrial conditions are investigated using a suite of uncoupled (Atmospheric Model Intercomparison Project; AMIP), fully coupled, and slab-ocean experiments ...
  • Bias in CMIP6 models as compared to observed regional dimming and brightening 
    Moseid, Kine Onsum; Schulz, Michael; Storelvmo, Trude; Julsrud, Ingeborg Rian; Oliviè, Dirk Jan Leo; Nabat, Pierre; Wild, Martin; Cole, Jason N.S.; Takemura, Toshihiko; Oshima, Naga; Bauer, Susanne E.; Gastineau, Guillaume (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Abstract. Anthropogenic aerosol emissions have increased considerably over the last century, but climate effects and quantification of the emissions are highly uncertain as one goes back in time. This uncertainty is partly ...
  • Overview of the Norwegian Earth System Model (NorESM2) and key climate response of CMIP6 DECK, historical, and scenario simulations 
    Seland, Øyvind; Bentsen, Mats; Oliviè, Dirk Jan Leo; Toniazzo, Thomas; Gjermundsen, Ada; Graff, Lise Seland; Debernard, Jens Boldingh; Gupta, Alok Kumar; He, Yan-Chun; Kirkevåg, Alf; Schwinger, Jörg; Tjiputra, Jerry; Aas, Kjetil Schanke; Bethke, Ingo; Fan, Yuanchao; Griesfeller, Jan; Grini, Alf; Guo, Chuncheng; Ilicak, Mehmet; Karset, Inger Helene H.; Landgren, Oskar Andreas; Liakka, Johan; Moseid, Kine Onsum; Nummelin, Aleksi; Spensberger, Clemens; Tang, Hui; Zhang, Zhongshi; Heinze, Christoph; Iversen, Trond; Schulz, Michael (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Abstract. The second version of the coupled Norwegian Earth System Model (NorESM2) is presented and evaluated. NorESM2 is based on the second version of the Community Earth System Model (CESM2) and shares with CESM2 the ...
  • Strong impacts on aerosol indirect effects from historical oxidant changes 
    Karset, Inger Helene H.; Berntsen, Terje Koren; Storelvmo, Trude; Alterskjær, Kari; Grini, Alf; Oliviè, Dirk Jan Leo; Kirkevåg, Alf; Seland, Øyvind; Iversen, Trond; Schulz, Michael (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Uncertainties in effective radiative forcings through aerosol–cloud interactions (ERFaci, also called aerosol indirect effects) contribute strongly to the uncertainty in the total preindustrial-to-present-day anthropogenic ...
  • Using Ice Cores to Evaluate CMIP6 Aerosol Concentrations Over the Historical Era 
    Moseid, Kine Onsum; Schulz, Michael; Eichler, Anja; Schwikowski, Margit; McConnell, Joseph R.; Oliviè, Dirk Jan Leo; Criscitiello, Alison S.; Kreutz, Karl J.; Legrand, Michel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The radiative effect of anthropogenic aerosols is one of the largest uncertainties in Earth's energy budget over the industrial period. This uncertainty is in part due to sparse observations of aerosol concentrations in ...
