The EU H2020 SafeSpace project aims to develop a prototype pipeline that connects several tools in a modular fashion to address the physics of the Sun – Interplanetary space – Earth’s magnetosphere with the ultimate goal to forecast radiation belts dynamics. We present a part of the pipeline called Helio1D that is dedicated to forecasting the solar wind properties at the Lagrangian L1 point. Helio1D models solar wind propagation using input data obtained from the MULTI-VP model, which itself models solar wind emergence near Sun based on magnetograms and coronal field reconstruction. In particular, we aim to forecast the properties of the regular solar wind, as well as Corotating Interaction Regions and their high-speed streams which are most geo-effective (for radiation belts in particular). We take an ensemble forecasting approach to provide optimum forecast up to 2 – 4 days of lead time. We also couple the Helio1D pipeline with neural network models that predict geomagnetic indices such as the Kp index for magnetospheric space weather forecasting. In this presentation, we will present the Helio1D pipeline status, as well as its benchmarking and calibration in order to provide optimum forecasting in real-time. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 870437.
