Updating the IRI ionospheric model for effects of substorms
Abstract
The effect of ionospheric disturbances occurring during a substorm or a sequence of substorm is modeled as an additive correction to the quiet IRI foF2 and hmF2 values which depends on the time since the onset of the substorm and on the maximum AE-index value reached in it. This can reduce the changes of hmF2 from 30 - 40% to 10 - 15%; the disturbed electron density profile is reproduced quite satisfactory too.
