Abstract: 

Multi-variable ensemble-based parameter and uncertainty estimation for a global hydrological model
Quantitative global-scale estimates of water flows and storage dynamics on the continents is required for understanding the Earth system as a whole and for supporting a sustainable management of water, food and energy in a globalized world. Global hydrological modeling has served these by combining a multitude of (model input) data with process understanding. However, it has not yet benefitted optimally from in-situ and remotely sensed observations of model output variables (e.g., streamflow, water storage, snow cover, open water area).  A flexible calibration (i.e. parameter estimation) and data assimilation methodology for global hydrological models is necessary to fully exploit observational data of multiple output variables but has not yet been developed. I present a first ensemble approach for multi-variable calibration of the global hydrological model WaterGAP that takes into account observation uncertainties and provides estimates of model output uncertainty.

Biography: 

Petra Döll earned a Master in Geology from the University of Colorado, Boulder, in 1987, a doctorate from the Technical University of Berlin in 1996 and a habilitation from the University of Kassel in 2002. She has been a Professor of Hydrology at Goethe University Frankfurt since 2003. She was lead author of two IPCC assessment reports. In 2019, she was awarded the Henry Darcy Medal of the European Geosciences Union. Her two research foci are 1) global-scale modeling of water resources and use under the impact of global change and 2) methods for transdisciplinary research and participatory processes.
