DST Indices - Reflection Variations in the Magnetospheric Tail Current and Field-aligned Currents in the Magnetosphere

The file is comprised of monthly DST indices. These indices are derived from a network of eight stations in the equatorial latitudes. Hourly DST indices provide an index of geomagnetic activity as a function of universal time. DST may reflect variations in the stratospheric tail current and field-aligned currents in the magnetosphere. The DST indices are available from 1957 to present.
