AbstractThe ambient solar wind that fills the heliosphere originates from multiple sources in the solar corona and is highly structured. It is often described as high-speed, relatively homogeneous, plasma streams from coronal holes and slow-speed, highly variable, streams whose source regions are under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify solar wind sources and understand what drives the complexity seen in the heliosphere.

Modeling the Solar Wind Speed: BRaVDA or MAS? Earlier in Section 2.1, we explored the difference in the solar wind structure near Earth for CR2077 where by HUXt propagated inner boundary speed conditions from MAS and BRaVDA. In summary, it was found that the data assimilated scheme was better at recreating the speed structures observed by ACE, especially for the duration and maximum speed of fast streams.
