Global Thermodynamic MHD Modeling of the Solar Corona in the Context of SDO/AIA Observations.
Abstract
Realistic magnetohydrodynamic (MHD) models can serve as powerful testbeds for exploring our understanding of magnetic and thermodynamic processes in the solar corona. An important aspect in their development is the use of observations to characterize model results. In this context we investigate the comparison of observations from the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) to a thermodynamic MHD model of the global corona (Lionello et al. 2009), with emphasis on exploiting the unique multi-spectral information available from the AIA observing program. We discuss the implications towards modeling multi-temperature magnetic structures observed in the low corona, and focus on the sensitivity of the AIA observables with respect to the choice of coronal heating parameterizations and magnetic boundary data.
