Overview

OpenIFS users can check their model installation with a short acceptance test on T21 resolution. The meteorological evaluation framework makes it possible to assess the meteorological performance of OpenIFS based on two sets of case studies.

Two weather events have been chosen to show the OpenIFS model capabilities and to provide reference cases for the userswhich had been predicted originally with different skill. 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.
