Data Access
The Equivalent Ionospheric Currents (EICs) data set contains horizontal ionospheric current data (Jx and Jy) derived using the SECS technique [Amm and Viljanen, Earth Planets Space, v. 51 pp. 431-440, 1999]. Positive Jx points to the geographic north pole. Positive Jy points to geographic east. The location of these currents is in geographic coordinates at 10s resolution. The distribution of these currents is not the same as the spherical elementary current amplitudes. The UT and date are obtained from the file name. For more information see Weygand et al. J. Geophys. Res. 116, A03305, doi:10.1029/2010JA016177, 2011.

Equivalent ionsheric current data produced over North America and Greenland
These data are the geographic location in units of degrees of the derived equivalent ionospheric current at 10 s resolution. The Altitude of the current vector is 100 km above the surface of the Earth.
Geographic Latitude and Longitude of the derived equivalent ionospheric current value.
These data are the Equivalent Ionospheric Currents (only the currents horizontal to the surface of the Earth: Jx and Jy) in units of mA/m at 10 s resolution. The Altitude of the current vector is 100 km above the surface of the Earth.
Jx of the derived equivalent ionospheric current value. Positive Jx points to the geographic north pole. Positive Jy points to geographic east.
