Rapid development of fast and flexible environmental models: the Mobius framework v1.0

Abstract. The Mobius model building system is a new open-source framework for fast and flexible environmental models. makes it possible researchers with limited programming experience to build performant models potentially complicated structures. can be easily interacted through the MobiView graphical user interface Python language. was initially developed support catchment-scale hydrology water-quality modelling but used represent any of hierarchically structured ordinary differential equations, such as population dynamics or toxicological Here, we demonstrate how quickly prototype several different structures dissolved organic carbon catchment use built-in auto-calibration statistical uncertainty analysis tools help decide on best Overall, hope modular platform offered by will provide step forward modelling, providing an alternative “one size fits all” paradigm. By making easier explore broader range parameterisations, users are encouraged more appropriate models, in turn this improves process understanding allows robust decision making.
