This archive contains input and output data extracted from the PPMLR-MHD simulations of the March 11, 2016 event. The files are: (a) Solar wind data files and the input file of the PPMLR-MHD code in the ‘solar_wind’ folder, which contains 5 files: (1) ‘B_clip.txt’: the magnetic field data; (2) ‘Ni_clip.txt’: the solar wind density data; (3) ‘Vi_clip.txt’: the solar wind speed data; (4) ‘Vthi_clip.txt’: the thermal velocity data; (5) ‘160311T1055_140m_wm’: the input file of the PPMLR-MHD code. (b) Data extracted from the output files of PPMLR-MHD simulations on March 11, 2016. The files are: (b1) The 'Tbhd_data' folder contains 51 sub-folders, with each folder representing one minute. The folder with the suffix '0000' represents the timestamp ‘12:20 on March 11, 2016’. Each 'Tbhdxxxx' sub-folder contains 7 files: (1) ‘key_parameter.mat’: key parameters in the magnetosphere; (2) ‘magnetopause_z0.mat’: the position of the magnetopause determined by open and closed magnetic field lines at the equatorial plane; (3) ‘magpause_p_z0.mat’: the position of the magnetopause determined by the pressure gradient at the equatorial plane; (4) ‘magpause_rho_z0.mat’: the position of the magnetopause determined by the density gradient at the equatorial plane; (5) ‘MI_coord_z0.mat’: the grid points on the equatorial plane and their corresponding magnetic latitude values; (6) ‘vazm.mat’: azimuthal velocity; (7) ‘xyz.mat’: the xyz coordinates of grid points in the magnetosphere. (b2) The 'Tbhp_data' folder contains 51 sub-folders, with each folder representing one minute. The folder with the suffix '0000' represents the timestamp ‘12:20 on March 11, 2016’. Each 'Tbhpxxxx' sub-folder contains 4 files: (1) ‘facn.mat’: field-aligned current in the northern hemisphere; (2) ‘jt.mat’: current on ionosphere and the corresponding location; (3) ‘key_parameter.mat’: key parameters in the ionosphere; (4) ‘xyz.mat’: the grid points in the ionosphere.本归档数据集包含从2016年3月11日事件的PPMLR-MHD磁流体动力学（Magnetohydrodynamics, MHD）模拟中提取的输入与输出数据。相关文件结构如下： (a) 太阳风数据文件与PPMLR-MHD代码的输入文件存储于‘solar_wind’文件夹内，该文件夹共包含5个文件： (1) ‘B_clip.txt’：磁场数据文件； (2) ‘Ni_clip.txt’：太阳风数密度数据文件； (3) ‘Vi_clip.txt’：太阳风速度数据文件； (4) ‘Vthi_clip.txt’：热速度数据文件； (5) ‘160311T1055_140m_wm’：PPMLR-MHD代码的输入配置文件。 (b) 2016年3月11日PPMLR-MHD模拟输出文件的提取数据，相关文件结构如下： (b1) ‘Tbhd_data’文件夹包含51个子文件夹，每个子文件夹对应一分钟的模拟时长。后缀为‘0000’的子文件夹对应时间戳‘2016年3月11日12:20’。每个‘Tbhdxxxx’子文件夹内含7个数据文件： (1) ‘key_parameter.mat’：磁层关键参数文件； (2) ‘magnetopause_z0.mat’：基于赤道面开闭磁力线判定的磁层顶位置数据文件； (3) ‘magpause_p_z0.mat’：基于赤道面压强梯度判定的磁层顶位置数据文件； (4) ‘magpause_rho_z0.mat’：基于赤道面数密度梯度判定的磁层顶位置数据文件； (5) ‘MI_coord_z0.mat’：赤道面网格点及其对应磁纬度值数据文件； (6) ‘vazm.mat’：方位角速度数据文件； (7) ‘xyz.mat’：磁层网格点的三维坐标数据文件。 (b2) ‘Tbhp_data’文件夹包含51个子文件夹，每个子文件夹对应一分钟的模拟时长。后缀为‘0000’的子文件夹对应时间戳‘2016年3月11日12:20’。每个‘Tbhpxxxx’子文件夹内含4个数据文件： (1) ‘facn.mat’：北半球场向电流数据文件； (2) ‘jt.mat’：电离层电流及其对应位置数据文件； (3) ‘key_parameter.mat’：电离层关键参数文件； (4) ‘xyz.mat’：电离层网格点的三维坐标数据文件。
