Plot of the SYM-H a as well as Swarm A IRI-2016 and SLIDEM \({{\varvec{M}}}_{{\varvec{e}}{\varvec{f}}{\varvec{f}}}\) estimates for the time around the 22 June 2015 storm, denoting the change in effective ion mass during this active time period. In this plot, \({{\varvec{M}}}_{{\varvec{e}}{\varvec{f}}{\varvec{f}}}\) estimates outside of the validity range of this parameter (i.e., at high latitudes) are omitted both for SLIDEM and for IRI-2016
