3D RT in a MURaM-ChE enhanced network simulation produces Mg II h&k lines closer to IRIS data than 1.5D, showing larger 1.5D-3D discrepancies than Bifrost due to horizontal velocities and more scatter in correlations.
Simulations identify photospheric magnetic field strength as the main driver of Mg II core line widths in quiet Sun regions, with non-equilibrium hydrogen ionization and 3D radiative transfer key in active regions.
