    • A novel initialization technique for decadal climate predictions 

      Volpi, Danila; Meccia, Virna L.; Guemas, Virginie; Ortega Montilla, Pablo; Bilbao, Roberto; Doblas-Reyes, Francisco; Amaral, Arthur; Echevarria, Pablo; Mahmood, Rashed; Corti, Susanna (Frontiers Media, 2021-07)
      Article
      Open Access
      Model initialization is a matter of transferring the observed information available at the start of a forecast to the model. An optimal initialization is generally recognized to be able to improve climate predictions up ...

    • Model evaluation of short-lived climate forcers for the Arctic Monitoring and Assessment Programme: a multi-species, multi-model study 

      Whaley, Cynthia H.; Mahmood, Rashed; von Salzen, Knut; Winter, Barbara; Eckhardt, Sabine (Copernicus Publications [, 2022-05)
      Article
      Open Access
      While carbon dioxide is the main cause for global warming, modeling short-lived climate forcers (SLCFs) such as methane, ozone, and particles in the Arctic allows us to simulate near-term climate and health impacts for a ...

    • Modelling the relationship between liquid water content and cloud droplet number concentration observed in low clouds in the summer Arctic and its radiative effects 

      Dionne, Joelle; Salzen, Knut von; Cole, Jason; Mahmood, Rashed; Leaitch, W. Richard; Lesins, Glen; Folkins, Ian; Chang, Rachel (European Geoscience Union, 2020-01-02)
      Article
      Open Access
      Low clouds persist in the summer Arctic with important consequences for the radiation budget. In this study, we simulate the linear relationship between liquid water content (LWC) and cloud droplet number concentration ...

    • Present and future aerosol impacts on Arctic climate change in the GISS-E2.1 Earth system model 

      Im, Ulas; Tsigaridis, Kostas; Faluvegi, Gregory; Langen, Peter L.; French, Joshua P.; Mahmood, Rashed; Thomas, Manu A.; Salzen, Knut von; Thomas, Daniel C.; Whaley, Cynthia H.; Klimont, Zbigniew; Skov, Henrik; Brandt, Jørgen (European Geosciences Union, 2021)
      Article
      Open Access
      The Arctic is warming 2 to 3 times faster than the global average, partly due to changes in short-lived climate forcers (SLCFs) including aerosols. In order to study the effects of atmospheric aerosols in this warming, ...

    • Toward consistent observational constraints in climate predictions and projections 

      Hegerl, Gabriele C.; Ballinger, Andrew P.; Booth, Ben B. B.; Borchert, Leonard F.; Brunner, Lukas; Donat, Markus; Doblas-Reyes, Francisco; Mahmood, Rashed (Frontiers Media, 2021-06)
      Article
      Open Access
      Observations facilitate model evaluation and provide constraints that are relevant to future predictions and projections. Constraints for uninitialized projections are generally based on model performance in simulating ...
