The solar chromosphere, lying between the photosphere and the transition to the corona, is one of the least under-stood parts of the Sun. This has to do with the difficulty in observing it , the chomosphere is dynamic on timescales of 10 seconds, the assumptions of local thermal equilibrium does not apply, and the plasma is expected to be out of statistical equilibrium, all of which makes the interpretation of the observations extremely difficult. The mechanisms behind the heating of the chromosphere and corona are not yet well understood. In this project we aim to understand the physics of the various chromospheric processes and phenomena resulting from small-scale dynamo generated solar magnetic fields. We will perform radiation magnetohydrodynamic (MHD) simulations including as much of the relevant physics as possible. This includes a study of any reconnection driven events that appear in the simulation, such as jets and impulsive heating. Additionally we will be able to study the dynamics behind observed physical phenomena, such as waves, shocks and spicules. These high-resolution detailed simulations are required to directly compare results with observations made with the latest generation of solar telescopes such as the 4m DKIST and the Sunrise balloon-borne observatory.
