Advancing our understanding of the chromosphere
Abstract
Recent progress has shown the solar chromosphere to be fundamentally dynamic, where non-linear techniques must be used to understand its nature. It is also the region where the magnetic field grows to dominate the plasma and where the coupling between radiation and matter becomes becomes quite tenuous. Understanding the workings of the chromosphere is vital if one is to understand the flow of energy between the solar surface and its outer atmosphere and wind. Recent numerical developments have shown that it is feasible to model the chromosphere, even to the extent that newly available high resolution observations sometimes can be reproduced in detail. We will discuss the challenges facing numerical chromospheric models and the observations needed to validate or refute them.
