| Overall, as a fundamental science research project, JET2SB will lead to the production of advanced knowledge in Sun-Earth-relationships physics with as main immediate deliverables peer-reviewed scientific publications. JET2SB will also have middle and long-term impacts on the related topic of solar wind origins, the exploitation of upcoming coronal observations instruments and the applied discipline of space weather. In terms of research strategy, the project will put the JET2SB partners, and thus France, in a pole position to carry further researches on the connections between the Sun and the heliosphere. | Overall, as a fundamental science research project, JET2SB will lead to the production of advanced knowledge in Sun-Earth-relationships physics with as main immediate deliverables peer-reviewed scientific publications.

| Comparison of the in-situ magnetic field and fluid measurement with the in-situ-like analyses of the simulation’s outputs will be carried out in WP3, LPC2E lead. Doing so, it will be possible to discriminate the WP2 simulations (and set-ups) that induce realistic SB signatures from those which don’t. The main objectives of WP3 is thus to provide forward constraints on the jet models, in order to iteratively reach a propagation model of solar jets able to account for diverse in-situ SB properties. | Comparison of the in-situ magnetic field and fluid measurement with the in-situ-like analyses of the simulation’s outputs will be carried out in WP3, LPC2E lead.
