Only hourly data is provided here. If you need minutes grade scaled parameter value, you can scale ionograms with IPSNET Ionogram Viewer online.

IPS uses the URSI parameter codes 55 and 56 for scaling range spread (Scaling R/S) and frequency spread (Scaling F/S).

The Multan data is kindly provided by the Space and Upper Atmosphere Research Commission (SUPARCO) of Pakistan. The Juliusruh data is kindly provided by the Leibniz-Institute of Atmospheric Physics e.V. at University of Rostock (IAP) of Germany. Their website and other space related websites can be found in WDC Links page.

All stations with CAPITAL NAMES only hold data files between 1957 and 1990 at present. All of these data files came from National Geophysical Data Center(NGDC) of USA.
