Towards an uncertainty framework for predictions in ungauged basins: The Uncertainty Working Group

The reduction of predictive uncertainty is the main objective and the main criterion of success for the Predictions in Ungauged Basins (PUB) initiative of IAHS. Achieving this goal requires that an uncertainty framework is created in which models, data and methods can be evaluated with respect to their impact on predictive uncertainty. Here we provide a first overview of the uncertainty working group, including its main objectives and how we intend to achieve them.
