Science Problems in the Middle Corona

Session ID#: 80208

Session Description:
Following the success of last year's inaugural middle corona session at AGU, that focussed on the instrumental aspect of observing this region. This year we focus specifically on science problems that can be addressed by studying this region. In particular we encourage talks that include observations and/or theories that cover the physics of this region including coronal mass ejection and solar wind acceleration, the interface between the open and closed corona, and the characteristics of the region around active regions, corona holes and the quiet sun, and how these vary throughout the solar cycle. We also encourage all presenters to consider planning for future missions, through single-mission or coordinated campaigns, to help answer these questions or test theories and help build community capacity to coordinate between different instruments to find different observations.
