Comparison between EUHFORIA simulation results at 1 au and ACE spacecraft data. From the top panel to the bottom panel, we present the number density, solar wind bulk speed, temperature, and pressure of the solar wind. The spacecraft data are indicated with a solid black line. Results for the EUHFORIA simulation where all the CMEs are injected are indicated with a solid red line, while the EUHFORIA simulation results where only CME 3 was injected are shown with a dashed blue line. The shaded area represents the combination of the results of the plasma parameters obtained from virtual spacecraft placed at ±5° in longitude and/or latitude from Earth for the run with all the CMEs.
