Work Package 2
- METRICS: How can we measure model performance in a climate change context?
- FRAMEWORKS: How should parameter estimation and evaluation be performed for changing climate using these metrics?
- ENSEMBLES: How do we select plausible members to create ensembles that encompass known uncertainties?
(a) Develop new set of metrics targeted to characterize reference data, climate model (CM), hydrological model (HM) and delta-change/bias-correction (DC/BC) method performance in simulating change in indicators
(b) Create a framework for calibration, evaluation and selection of ensemble members (both for HM members or CM members) and DC/BC methods relevant to climate indicators
(c) Demonstrate the new methods for users of both local and pan-European climate services for the water sector.
In this workpackage we research how to increase the quality and usability of climate services. We address the research questions specifically for different indicators (e.g. 50-year return period flood, mean annual snow maximum) and different locations and address the whole climate impact modelling chain from choice of reference data used to describe today’s climate, via climate models, adjustment methods and impact modelling.
