A new reconstruction of the Dst index for 1932-2002
We have reconstructed a new, homogeneous geomagnetic Dst index for 1932-2002, thus extending the original Dst index by 25 years, i.e.by more than Garden Bridges one full solar magnetic cycle.The extension was done by using data from the original set of four low-latitude stations for 1941-1956, and by using the nearby CTO station as a predecessor of
