Nighttime geomagnetic response to jumps of solar wind dynamic pressure: A possible cause of Québec blackout in March 1989

<p>This contains the original simulation data used by the paper &#39;Nighttime geomagnetic response to jumps of solar wind dynamic pressure: &nbsp;A possible cause of Qu&eacute;bec blackout in March 1989&#39;, which will appear in Space Weather. The data were obtained by the global MHD simulation (REPPU).</p> <p>Each sav file (IDL saveset format) contains the physical variables in the ionosphere at each grid point (mlt*mlat: 321*221, starting at 0 MLT and -90 MLAT) for Run 02n, 30n, 30s, 33n, and 33s, including</p> <ul> <li>MHD time series (&#39;time&#39; in minutes),</li> <li>field-aligned current (&#39;fac1&#39; in A/m2),</li> <li>electric potential (&#39;pot&#39; in V),</li> <li>ionospheric conductivities (&#39;ss11&#39;, &#39;ss12&#39;, and &#39;ss22&#39; in S).</li> </ul> <p>The sav file can be opened by IDL. By typing, for example,<br> IDL&gt; restore,&#39;run02n.sav&#39;<br> you can load the file to the memory of IDL. Type &#39;help&#39; to confirm the variables that are loaded.</p>
