We validated these model chains to see if they meet the needs of the ESA SWE portal user base which is broader than the space weather research and forecasting community and also includes various stakeholders who are affected by space weather in some way. Through our validation of the integrated models we want to make sure that users can only obtain sensible and accurate results and that the different models coupled together still give accurate results. We have mainly validated these coupled models by comparing the final model’s output with measurement data calculating multiple metrics selected for the different insights they provide. The validated model chains will be utilised in daily space weather forecast runs made available within the SSA SWE network with resulting predictions of the environment and its effects propagated to the user community 3UE_VSWMC/ 3UE_VSWMC/ 3UE_VSWMC STCE VSWMC The 17th European Space Weather Week Glasgow robbe.vansintjan@observatoire.be http://esww17.iopconfs.org/cd04 1236346 http://publi2-as.oma.be/record/5458/files/ESWW17Pres_VSWMC_validation_activities.pptx Invited CTALKINVI
