dc.description.abstractThis paper discusses the ability of the International Reference Ionosphere IRI-2007 storm time model to predict foF2 ionospheric parameter during geomagnetic storm periods. Experimental data (based on availability) from two low latitude stations: Vanimo (geographic coordinates, 2.7°S, 141.3°E, magnetic coordinates, 12.3°S, 212.50°E) and Darwin (geographic coordinates, 12.45°S, 130.95°E, magnetic coordinates, 22.9°S, 202.7°E) during nine storms that occurred in 2000 (Rz12 = 119), 2001(Rz12 = 111) and 2003 (Rz12 = 64) are compared with those obtained by the IRI-2007 storm model. The results obtained show that the percentage deviation between the experimental and IRI predicted foF2 values during these storm periods is as high as 100% during the main and recovery phases. Based on the values of “relative deviation module mean” (RDMM) obtained (i.e. between 0.08 and 0.60), it is observed that there is a reasonable to poor agreement between measured foF2 values and the IRI-storm model prediction values during main and recovery phases of the storms under investigation. As a result, in addition to other studies that have been carried out from different sectors, more studies are required to be carried out. This will enable IRI community to improve on the present performance of the model. In general, the IRI-storm model predictions follow normal trend of the foF2 measured values but does not reproduce well the measured values.en_US
