  • Gruber, Simon; Blahak, Ulrich; Haenel, Florian; Kottmeier, Christoph; Leisner, Thomas; Muskatel, Harel; Storelvmo, Trude; Vogel, Berhnard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    In this study, cloud‐resolving simulations of a case study for a limited area of the hibernal Arctic were performed with the atmospheric modeling system ICON‐ART (ICOsahedral Nonhydrostatic‐Aerosol and Reactive Trace gases). ...
  • 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 ...
  • Bellouin, Nicolas; Quaas, Johannes; Gryspeerdt, Edward; Kinne, Stephan A.; Stier, Philip; Watson-Parris, Duncan; Boucher, Oliviér; Carslaw, Kenneth S.; Christensen, Matthew W.; Daniau, Anne-Laure; Dufresne, Jean-Louis; Feingold, Graham; Fiedler, Stephanie; Forster, Piers Maxwell; Gettelman, Andrew; Haywood, Jim M.; Lohmann, Ulrike; Malavelle, Florent F.; Mauritsen, Thorsten; McCoy, Daniel T.; Myhre, Gunnar; Mülmenstädt, Johannes; Neubauer, David; Possner, Anna; Rugenstein, Maria A.A.; Sato, Yousuke; Schulz, Michael; Schwartz, Stephen E.; Sourdeval, Odran; Storelvmo, Trude; Toll, Velle; Winker, David M.; Stevens, Björn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Aerosols interact with radiation and clouds. Substantial progress made over the past 40 years in observing, understanding, and modeling these processes helped quantify the imbalance in the Earth's radiation budget caused ...
  • Storelvmo, Trude; Kristjansson, Jon Egill; Muri, Helene Østlie; Pfeffer, Melissa Anne; Barahona, Diego; Nenes, A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    Cirrus clouds, thin ice clouds in the upper troposphere, have a net warming effect on Earth's climate. Consequently, a reduction in cirrus cloud amount or optical thickness would cool the climate. Recent research indicates ...
  • Muri, Helene Østlie; Kristjansson, Jon Egill; Storelvmo, Trude; Pfeffer, Melissa Anne (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    The climatic effects of climate engineering—or geoengineering—via cirrus cloud thinning are examined. Thinner cirrus clouds can allow more outgoing longwave radiation to escape to space, potentially cooling the climate. ...
  • Phillips, Peter C. B.; Leirvik, Thomas; Storelvmo, Trude (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    How sensitive is Earth’s climate to a given increase in atmospheric greenhouse gas (GHG) concentrations? This long-standing question in climate science was recently analyzed by dynamic panel data methods using extensive ...
  • Tan, Ivy; Storelvmo, Trude (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Underestimation of the proportion of supercooled liquid in mixed‐phase clouds in climate models has called into question its impact on Arctic climate change. We show that correcting for this bias in the CESM model can ...
  • Karset, Inger Helene H.; Gettelman, Andrew; Storelvmo, Trude; Alterskjær, Kari; Berntsen, Terje Koren (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    While most observations indicate well-buffered clouds to aerosol perturbations, global models do not. Among the suggested mechanisms for this discrepancy is the models' lack of connections between cloud droplet size and ...
  • Storelvmo, Trude; Heede, Ulla; Leirvik, Thomas; Phillips, Peter; Arndt, Philipp; Wild, Martin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The global temperature trend observed over the last century is largely the result of two opposing effects—cooling from aerosol particles and greenhouse gas warming. While the effect of increasing greenhouse gas concentrations ...
  • 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 ...
  • Takeishi, Azusa; Storelvmo, Trude (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    The impacts of enhanced heterogeneous ice nucleation (HET) on the properties of deep convective clouds (DCCs) have been investigated in cloud‐resolving simulations with the WRF‐CHEM model. The study focuses on a case ...

M.; Irvine, Peter J.; Jones, Andy; Lawrence, Mark G.; MacCracken, Michael; Muri, Helene; Moore, John C.; Niemeier, Ulrike; Phipps, Steven J.; Sillmann, Jana; Storelvmo, Trude; Wang, Hailong; Watanabe, Shingo (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    We present a suite of new climate model experiment designs for the Geoengineering Model Intercomparison Project (GeoMIP). This set of experiments, named GeoMIP6 (to be consistent with the Coupled Model Intercomparison ...
