Monitoring and forecasting the regional water cycle with the Terrestrial Systems Modelling Platform (TSMP): Overview and first evaluation results

The Terrestrial Systems Modelling Platform (TSMP, https://www.terrsysmp.org) is a scale-consistent, highly modular, massively parallel, physics-based integrated, coupled regional Earth system model. In its current production mode TSMP features the Consortium for Small-scale Modeling (COSMO) atmospheric model, the Community Land Model (CLM), and the hydrologic model ParFlow, linked through the OASIS3-MCT coupler. Driven by ECMWF forecasts, a monitoring and forecasting setup (TSMP-M) provides daily 10-day deterministic forecasts of the terrestrial hydrological cycle from regional to continental scales for a 12.5-km pan-European domain and a smaller convection-permitting km-resolution domain over North-Rhine Westphalia, Germany. The unique TSMP-M provides all states and fluxes from groundwater to the top of the atmosphere. Here we present an overview of TSMP-M and an evaluation of its performance as a monitoring system against observations
