The increasing volume of climate model data makes the use of traditional analysis tool impractical. This hinders the discovery of new crucial knowledge for society. COLUMBIA initiates a multidisciplinary research activity that will result in a cutting-edge customizable methodology that aims to facilitate rigorous evaluation of large ensemble of Earth system models. The innovative assessment tool will be based on combining Machine Learning with robust statistics and multiple process-oriented assessments, and aims to filter ‘good’ models from the rest and thereby increase our confidence when synthesizing future climate change projections.
