Data of two-cell convection

This archive contains data extracted from the simulated data files of PPMLR-MHD code on March 11, 2016. The files are:

• 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, which are: (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. 
• 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, which are: (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.
