LWS TR&T Focus Teams:
Exploring the Magnetic Connection Between the Photosphere and Low Corona
Team Chair: Alphonse Sterling
Target Description: Many LWS models of the corona and heliosphere depend on boundary conditions at the coronal base (the lowest altitude where the plasma beta is small), yet observations of the magnetic field come mostly from the photosphere below. It is therefore vital to understand how the magnetic field maps from the photosphere, through the chromosphere and transition region, and into the corona. This region of the atmosphere is also important for other reasons. For example, much of the UV radiation that drives the ionosphere/thermosphere system originates in the chromosphere and is determined by the chromospheric heating and structure.
Goals and measures of success: The measures of success for this topic are the impact of the science advances made by the team in improving the predictive capabilities of our current models.
solicited investigations: This group will include theoreticians, numerical modelers, and observers. Proposals which address this topic should use high resolution magnetograms directly or couple with other team models which do so. Examples of investigations which are encouraged include:
