Time series of all variables extracted in the 2D photospheric plane from a 3D MHD simulation of an emerging flux rope

Data extracted at dt=0.25 intervals from the ground truth simulation used as input to the data-driven simulation described in Tarr+2026 ApJ (ApJ DOI: https://doi.org/10.3847/1538-4357/ae40f4, arxiv DOI: https://doi.org/10.48550/arXiv.2601.09804). Data files are distributed in hdf5 format (*.h5 extension) and are packaged in sets of 100 files in zip archive, corresponding to times t=0.0-24.75, 25.0-49.75, etc. The ground truth simulation corresponds to the theta=pi case from Leake+2022 ApJ 934,10 (doi.org/10.3847/1538-4357/ac74b7). Variables are extracted from the constant z=0.0 plane corresponding to the model photosphere. All variables are colocated on a cell centered grid after being averaged to that location, as necessary. Simulations were performed using versions 2.5 (GT) and 2.10 (DD) of the LaRe3D MHD code本数据集以dt=0.25为间隔提取数据，数据来源于Tarr等人2026年发表于《天体物理学杂志》（Astrophysical Journal，简称ApJ）的文献中所描述的数据驱动模拟的输入真值模拟，相关文献DOI：https://doi.org/10.3847/1538-4357/ae40f4，arXiv预印本DOI：https://doi.org/10.48550/arXiv.2601.09804。 数据文件以HDF5格式存储（扩展名为*.h5），每100个文件打包为一个ZIP压缩包，对应时间区间依次为t=0.0~24.75、25.0~49.75等。 该真值模拟对应Leake等人2022年发表于《天体物理学杂志》934卷10期的文献中θ=π的场景，文献DOI：https://doi.org/10.3847/1538-4357/ac74b7。所有变量提取自对应模型光球层的z=0.0恒定平面，经必要的空间平均后，均位于网格单元中心位置上。 本模拟分别采用LaRe3D磁流体动力学（MHD）代码的2.5版本（真值模拟，GT）与2.10版本（数据驱动模拟，DD）完成。
