Modification of solar activity indices in the International Reference Ionosphere IRI and IRI-Plas models due to recent revision of sunspot number time series
The International Reference Ionosphere (IRI) imports global effective ionospheric IG12 index based on ionosonde measurements of the critical frequency foF2 as a proxy of solar activity. Similarly, the global electron content (GEC), smoothed by the sliding 12-months window (GEC12), is used as a solar...
