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

This contains the original simulation data used by the paper 'Nighttime geomagnetic response to jumps of solar wind dynamic pressure:  A possible cause of Québec blackout in March 1989', which will appear in Space Weather. The data were obtained by the global MHD simulation (REPPU).

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

MHD time series ('time' in minutes),

field-aligned current ('fac1' in A/m2),

electric potential ('pot' in V),

ionospheric conductivities ('ss11', 'ss12', and 'ss22' in S).

The sav file can be opened by IDL. By typing, for example,
IDL> restore,'run02n.sav'
you can load the file to the memory of IDL. Type 'help' to confirm the variables that are loaded.
