EUHFORIA (EUropean Heliospheric FORecasting Information Asset) is a space weather modeling tool that computes the time-evolution of the inner heliospheric plasma environment using a combination of empirical and physics-based modeling approaches. EUHFORIA consists of two major components: A coronal model and a heliosphere model including several types of coronal mass ejections. The coronal model provides data-driven solar wind plasma parameters at 0.1 AU by constructing a magnetic field model of the coronal large-scale magnetic field and employing empirical relations to determine the plasma state such as the solar wind speed and mass density. These are then used as boundary conditions to drive a three-dimensional time-dependent magnetohydrodynamics model of the inner heliosphere up to 2 AU.
The goal of EUHFORIA is to be a next-generation space weather prediction model that aids in mitigating the effects of space weather on European technological assets as well as assists in science operations of future space missions.
The EU-funded EUHFORIA 2.0 will address geoeffectiveness, impacts and mitigation, including extreme events, related to solar eruptions, solar wind streams and Solar Energetic Particles, with particular emphasis on its application to forecast Geomagnetically Induced Currents (GICs) and radiation on geospace.
