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.

Processing Steps
  • 2015-04-22T00:00:00 - NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.

Processing Steps
  • DST data are obtained from Kyoto when available. Daily means are computed and the data are reformated and added to the appropriate annual file.
