Heliospheric Weather Expert Service Centre

The mission of the Heliospheric Weather Expert Service Centre (H-ESC) is to provide and develop the functionalities, capabilities and expertise in the domain of Heliospheric Weather that are needed within the ESA SSA SWE network to achieve as a collaborative enterprise its mission of demonstrating and assessing the influences of Space Weather and informing and supporting end users through the provision of accurate, reliable and timely products and (pre-)operational services, tailored to their requirements.
The specific goal of the Heliospheric Expert Service Centre (H-ESC) is to fully exploit heliophysics assets and expertise from Europe, and further afield, to provide, improve and support the provision of alerts, forecasts and post event analysis of space weather conditions both near to the Earth and at other locations within the heliosphere. This will be accomplished through the use of remote-sensing and in-situ monitoring to identify and track key transient features (including coronal mass ejections, high-speed solar wind streams and solar energetic particles), combined with the use of advanced modelling and analysis techniques to predict their arrival at various points of interest in the heliosphere.
