Description
The southern auroral electrojet (SAE) index is constructed from 7 ground magnetometers in the southern auroral region. This data set contains a southern auroral electrojet (SAE) index, a southern auroral lower (SAL) index, and a southern auroral upper (SAU) index. Availability of the SAE index may vary from day to day depending upon magnetometer data availabiliy. SAE indices were only produced when data from all stations were available. Details on the magnetometer arrays are available at: Weygand, J.M., and E. Zesta, Comparison of auroral electrojet indices in the Northern and Southern hemispheres, J. Geophys. Res., 113, A08202, doi:10.1029/2008ja013055, 2008.

Southern Auroral Electrojet Lower Index
ParameterKey
SAL index
Description
These data are the southern auroral electrojet lower index in units of nT at 60 s resolution. These values were determined using the same method as the World Data Center AL index.
Caveats
The 5 quiest days were not alway available from the ground magnetometers. The next available quietest day was used instead. Also be aware of spikes in the data from original magnetometer data sets.
