The purpose of this workshop was to foster the development of tools to interpret current and future measurements of coronal magnetic fields in order to improve our understanding of the Sun and the sources of Space Weather. This was motivated by the anticipated rapid growth over the next decade in our remote sensing capabilities of the coronal plasma. The Coronal Multi-channel Polarimeter instrument is now obtaining routine measurements of coronal magnetic fields, and improved measurements are on the horizon in the visible to IR spectral regions with the construction of the Advanced Technology Solar Telescope, and in the radio region through the upgrade of the Owens Valley Solar Array and the construction of the Chinese Spectral Radioheliograph. In addition, proposed instruments like the Coronal Solar Magnetism Observatory, the Frequency Agile Solar Radiotelescope, the Interface Region Imaging Spectrograph, and the Solar Magnetism Explorer promise comprehensive and routine measurements of coronal fields and plasma with observations ranging from EUV to radio wavelengths. These new capabilities can only be exploited with improvements in our ability to model the polarized radiative transfer through the coronal plasma and by coupling information on the coronal magnetic field and plasma conditions with models extending to the near Earth environment. This workshop included a wide variety of subjects including, but not limited to, instrumentation, the interpretation of polarimetric signals in EUV and UV emission lines, techniques to mitigate the effects of line-of-sight integration effects of the optically thin corona such as tomographic inversions and forward modeling, models of the polarized radiative transfer at radio wavelengths, extrapolation and MHD modeling of coronal magnetic fields, as well as discussions on how to move forward with coupling these inferences of the coronal plasma with models of heliospheric structure and Space Weather prediction.

The workshop was held over a three day period and consisted of invited talks, and contributed oral and poster presentations. We intend to publish the proceedings of the workshop as a topical issue of the journal Solar Physics. A limited amount of financial support was available. Poster sessions were held in the early evenings of Monday and Tuesday and were accompanied by complementary food and beverages.


The meeting was held at the Foothills Laboratory of the National Center for Atmospheric Research in Boulder, CO.
