GPS and IRI Comparison

The graphs above show the comparison between GPS-derived TEC and IRI/foF2 TEC values above the stations on the day shown in the figures. The comparison provides information on the TEC accuracy of the IRI model.

GPS-based TEC values are derived from the GPS observations by the Australian Regional GPS Network (ARGN) which is operated by the National Mapping Division (formerly AUSLIG) of GEOSCIENCE AUSTRALIA.

IRI/foF2 TEC values are computed by using the IRI-90 model, with auto-scaled foF2 ionosonde data observed in Australian region as the input parameter to the model.
