GloFAS v5 renalysis and forecasts are generated using LISFLOOD OS, a physically based spatially distributedrainfall-runoff-routing hydrological model. OS LISFLOOD hydrological modelling suite, including a set of tools for model set-up, parameter calibration, and results post-processing is described in Grimaldi et al. [SUBMITTED]. Detailed technical information about modelled physical processes is available OS LISFLOOD model documentation.

Specifically, GloFAS v5 benefits of the improvements of LISFLOOD OS v5.0.0, an upgraded version compared to LISFLOOD OS v4.1.1, which was used to produce GloFASv4.
