  • Training of supermodels - in the context of weather and climate forecasting 

    Schevenhoven, Francine (Doctoral thesis, 2021-02-08)
    Given a set of imperfect weather or climate models, predictions can be improved by combining the models dynamically into a so called `supermodel'. The models are optimally combined to compensate their individual errors. ...
