Data of two-cell convection

<p>This archive contains input and output data extracted from the PPMLR-MHD simulations of the March 11, 2016 event. The files are:</p> <p>(a)&nbsp;Solar wind data&nbsp;files and the input file of the PPMLR-MHD&nbsp;code&nbsp;in the &lsquo;solar_wind&rsquo; folder, which&nbsp;contains 5&nbsp;files:</p> <p>(1)&nbsp;&lsquo;B_clip.txt&rsquo;: the magnetic field data;</p> <p>(2)&nbsp;&lsquo;Ni_clip.txt&rsquo;: the solar wind density data;</p> <p>(3)&nbsp;&lsquo;Vi_clip.txt&rsquo;: the solar wind speed data;</p> <p>(4)&nbsp;&lsquo;Vthi_clip.txt&rsquo;: the thermal velocity&nbsp;data;</p> <p>(5)&nbsp;&lsquo;160311T1055_140m_wm&rsquo;: the input file of the PPMLR-MHD&nbsp;code.</p> <p>(b) Data extracted from the output files of PPMLR-MHD simulations on March 11, 2016. The files are:</p> <p>(b1) The 'Tbhd_data' folder contains 51&nbsp;sub-folders, with each folder representing one minute.
