The effect of rapid adjustments to halocarbons and N2O on radiative forcing
Hodnebrog, Øivind; Myhre, Gunnar; Kramer, Ryan J.; Shine, Keith P.; Andrews, Timothy; Faluvegi, Greg; Kasoar, Matthew; Kirkevåg, Alf; Lamarque, Jean-Francois; Mülmenstädt, Johannes; Oliviè, Dirk Jan Leo; Samset, Bjørn Hallvard; Shindell, Drew; Smith, Christopher J.; Takemura, Toshihiko; Voulgarakis, Apostolos (Journal article; Peer reviewed, 2020)Rapid adjustments occur after initial perturbation of an external climate driver (e.g., CO2) and involve changes in, e.g. atmospheric temperature, water vapour and clouds, independent of sea surface temperature changes. ... -
Historical total ozone radiative forcing derived from CMIP6 simulations
Skeie, Ragnhild Bieltvedt; Myhre, Gunnar; Hodnebrog, Øivind; Cameron-Smith, Philip J.; Deushi, Makoto; Hegglin, Michaela I.; Horowitz, Larry W.; Kramer, Ryan J.; Michou, Martine; Mills, Michael J.; Oliviè, Dirk Jan Leo; O’Connor, Fiona M.; Paynter, David; Samset, Bjørn Hallvard; Sellar, Alistair; Shindell, Drew; Takemura, Toshihiko; Tilmes, Simone; Wu, Tongwen (Journal article; Peer reviewed, 2020)Radiative forcing (RF) time series for total ozone from 1850 up to the present day are calculated based on historical simulations of ozone from 10 climate models contributing to the Coupled Model Intercomparison Project ... -
Observational Evidence of Increasing Global Radiative Forcing
Kramer, Ryan J.; He, Haozhe; Soden, Brian J.; Oreopoulos, Lazaros; Myhre, Gunnar; Forster, Piers M.; Smith, Christopher J. (Journal article; Peer reviewed, 2021)Changes in atmospheric composition, such as increasing greenhouse gases, cause an initial radiative imbalance to the climate system, quantified as the instantaneous radiative forcing. This fundamental metric has not been ... -

Myhre, Gunnar; Samset, Bjørn Hallvard; Forster, Piers M.; Hodnebrog, Øivind; Sandstad, Marit; Mohr, Christian Wilhelm; Stjern, Camilla Weum; Sillmann, Jana; Andrews, Timothy; Boucher, Olivier; Faluvegi, Gregory; Iversen, Trond; Lamarque, Jean-Francois; Kasoar, Matthew; Kirkevåg, Alf; Kramer, Ryan J.; Liu, Longbo; Mülmenstädt, Johannes; Oliviè, Dirk Jan Leo; Quaas, Johannes; Richardson, Thomas B.; Shawki, Dilshad; Shindell, Drew; Smith, Chris; Stier, Philip; Tang, Tao; Takemura, Toshihiko; Voulgarakis, Apostolos; Watson-Parris, Duncan (Peer reviewed; Journal article, 2022)This data descriptor reports the main scientific values from General Circulation Models (GCMs) in the Precipitation Driver and Response Model Intercomparison Project (PDRMIP). The purpose of the GCM simulations has been ... -
Surface warming and wetting due to methane’s long-wave radiative effects muted by short-wave absorption
Allen, Robert J.; Zhao, Xueying; Randles, Cynthia A.; Kramer, Ryan J.; Samset, Bjørn Hallvard; Smith, Christopher J. (Peer reviewed; Journal article, 2023)Although greenhouse gases absorb primarily long-wave radiation, they also absorb short-wave radiation. Recent studies have highlighted the importance of methane short-wave absorption, which enhances its stratospherically ...
