SPIN4D Data Release 1

This is the Critical Early DKIST Science: Spectropolarimetric Inversion in Four Dimensions with Deep Learning (SPIN4D) "Data Release 1" (SPIN4D-DR1). This dataset is a 13TB subset of 109TB of simulations that accompanied our first paper (DOI 10.3847/1538-4357/ad865b). We performed simulations of the small-scale dynamo actions that are prevalent in quiet-Sun and plage regions using Rempel's 2014 version of the Max-Planck University-of-Chicago Radiative MHD code (MURaM). Six simulation cases with different mean magnetic fields were conducted. These are: SPIN4D_SSD, SPIN4D_SSD_100G, SPIN4D_SSD_200G, SPIN4D_SSD_50G, SPIN4D_SSD_50G_V, SPIN4D_SSD_Large. Each case covers six solar-hours with output snapshots stored at a 40s cadence. For each case we forward model the Stokes profiles for two sets of Fe I lines at 630 and 1565 nm for snapshots at 12 minute intervals with two opposite magnetic field orientations due to the inherent LOS ambiguity.
