Abstract

A brief review is provided of what has been learned about the solar corona from existing coordinated radio and EUV (or soft X-ray) observations. Topics include: introduction to radio thermal bremsstrahlung and thermal gyroemission; two-dimensional coronal magnetography measurements; measurements of coronal elemental abundances; measurements of physical properties of quasitransverse (QT) layers in the coronal magnetic field; and three-dimensional coronal magnetography measurements (the primary subject of this Chapter). Results from these studies are used to help focus on coronal diagnostics that can be performed with similar coordinated observations involving FASR, as well as to recommend FASR instrument requirements.
