Abstract The launches of Parker Solar Probe (Parker) and Orbiter (SolO) are enabling a new era solar wind studies that track the from its origin at photosphere, through corona, to multiple vantage points in inner heliosphere. A key ingredient for these models is input photospheric magnetic field map provides boundary condition coronal portion many heliospheric models. In this paper, we perform steady-state, data-driven magnetohydrodynamic (MHD) simulations during Carrington rotation 2258 with Grid GAMERA model. We use ADAPT AFT flux transport quantitatively assess how well each model matches situ measurements Parker, SolO, Earth. find both reproduce components well. At SolO Earth, reproduced relatively well, though not as density extremely poorly. velocity overpredicted but or hinting Wang–Sheeley–Arge (WSA) relation, fine-tuned misses deceleration near Sun. conclude performs similarly all cases, comparable purely WSA treatment no MHD component. Finally, trace lines back an active region outflow was observed by Hinode/EIS, which shows evidence elevated charge state ratios.
