The geomagnetic equatorial Dst index at 1-hr time resolution, derived at World Data Center for Geomagnetism, Kyoto, Kyoto University. The real-time Dst index is only for monitoring, diagnostics, and forecasting purposes. Since the values are derived from unverified raw data, they may contain inaccuracies. The observatories as well as we have no responsibility for inaccuate values caused by noises and baseline shifts. Hourly values given here will be replaced by provisional and final values at later dates. Users are advised to use the provisional Dst index or the final Dst index for scientific analysis.

Time is expressed with year, month, day, and hour, each stored in integer format. Details of the data record format is described at http://wdc.kugi.kyoto-u.ac.jp/dstae/format/dstformat.html
The Dst index is calculated by the sum of base value (unit 100nT) and 24 hourly value (unit 1nT). Details of the data record format is described at http://wdc.kugi.kyoto-u.ac.jp/dstae/format/dstformat.html
