Abbreviations:
- ISM - Ionospheric Scintillation Monitor
- TEC - Total Electron Content
- Lat - station latitude (decimal degrees)
- Long - station longitude (decimal degrees)
- GLat - geomagnetic latitude of the station
- GLon - geomagnetic longitude of the station
- LSTM: Local Standard Time Meridian, The (LSTM) is calculated according to the equation: LSTM =15°·ΔTGMT. where ΔTGMT is the difference of the Local Time (LT) from Greenwich Mean Time (GMT) in hours. 15°= 360°/24 hours.
- Open - date at which the equipment commenced operating
- Closed - date at which the equipment ceased operating
