Overview

Two weather events have been chosen to show the OpenIFS model capabilities and to provide reference cases for the users. Several model experiments were carried out to test the effect of starting date, forecast length, initial condition as well as spatial resolution on the forecast quality. The model outputs are visualized and evaluated using Metview.

After introduction of the two cases, this section guides the user step by step through running the selected experiments, post-processing the model outputs, downloading the reference data and visualising the model outputs with Metview. A gallery from the prepared figures is also included. The input data and the namelists needed for the model runs, the scripts for the MARS retrieves, the Metview macros for visualization and the output figures are available for download on the ECMWF download server.
