Executive editor

The study provides a unique effort undertaken by several research groups in the context of a remarkably instrumented large scale system. The latter is subject to a variety of measurement approaches and techniques and a wide range of models are considered in a remarkable inter-comparison study. Key methodological elements stemming from this very comprehensive work are highly relevant to the broad hydrological community.

Short summary

Model intercomparison studies are carried out to test various models and compare the quality of their outputs over the same domain. In this study, 13 diverse model setups using the same input data are evaluated over the Great Lakes region. Various model outputs – such as streamflow, evaporation, soil moisture, and amount of snow on the ground – are compared using standardized methods and metrics. The basin-wise model outputs and observations are made available through an interactive website.
