EUHFORIA simulations compared with in situ data. Top to bottom: solar wind speed, density, temperature, total magnetic field, and its three components. In all panels, the observations from Wind spacecraft (black dots) and EUHFORIA simulation results are given for Case 1 (green), Case 2 (blue), and Case 3 (red). The vertical dotted red line shows the launch time of the Main CME event from the Sun. Grey and green shaded areas correspond to the duration of the First and Main CME’s impact at Earth.
