Dataset of Solar Wind Shocks and GICy-indices for Solar Cycle 23

<p>Dataset of solar wind shocks and GIC<em>_y</em>-indices for solar cycle 23 obtained&nbsp;using ACE satellite solar wind data and geomagnetic field measurements from&nbsp;the Australian region. Columns 1&nbsp;and 2&nbsp;show the date and decimal time (hours UT) of the solar wind shock. Columns 3-17&nbsp;show the pre-shock (minimum values), the post-shock (maximum values), and the calculated step change for solar wind velocity (km/s), density (cm^-3), temperature (&deg;K), magnetic field strength (nT), and dynamic pressure (nPa) respectively. Columns 18-24&nbsp;show the geomagnetic field observing station, geographic longitude and latitude, geomagnetic longitude and latitude, decimal time (hours UT), and GIC<em>_y</em>-index values associated with the shock parameters of columns 1-17.</p>
