15. Potential field source surface “breathes” over the course of the solar cycle

Contributed by WIlliam Arden. Posted on May 15, 2014

Our results show that raising the source surface height 15-30% during solar minimum (depending on the model used) better reproduces the observed IMF open flux from OMNI. We used two different PFSS models and the MDI/HMI magnetograms as input.
