This is the geomagnetic storm list generated using the same method as for the paper 'SuperDARN observations during geomagnetic storms, geomagnetically active times and enhanced solar wind driving', by M.-T. Walach & A. Grocott, published in JGR, 2019, doi:10.1029/2019JA026816.
The list was generated using an algorithm and is based on Sym-H. The event list is an extension of https://doi.org/10.17635/lancaster/researchdata/622
