SH22A:
Magnetic Fields in the Solar Corona: Observations and Modeling I


Submit an Abstract to this Session


Session ID#: 61221

Session Description:
The coronal magnetic field is the source of many of the fascinating phenomena studied in heliophysics, but its high temperature, low density, the large range of spatial scales of interest, and its highly dynamic nature make it quite difficult to measure.  This paucity of measurements makes it difficult to evaluate the accuracy of coronal models.  Efforts to measure, model, and predict the coronal magnetic field will be critical to understanding the evolution of plasma in the inner heliosphere in the era of Parker Solar Probe and Solar Orbiter.  We invite submissions that describe recent efforts to characterize the coronal magnetic field through either models or observation, with a particular interest in works that use one to enhance or understand the other.  We also invite submissions that describe the additional data and/or projects needed to advance this topic.
