Studying and understanding the Sun is essential because it serves in understanding the rest of the astronomical universe. It is the source of solar wind (a magneto-ionic gas) that streams past the Earth at velocities of more than 400 km/s. Thus changes/disturbances in the solar wind have a large impact on the Earth's magnetic field. In this study, we have analyzed solar wind speed estimates obtained from Interplanetary Scintillation (IPS) measurements. These results are compared with Wang-Sheeley-Arge (WSA) model to predict the solar wind flow and interplanetary magnetic field. We also present time-dependent MHD simulations of the solar wind flow from 0.1 AU to 1 AU obtained with the boundary conditions based on both IPS and WSA data.
