Interpretation of experimental data on HF propagation on the St. Petersburg-Spitsbergen path

Using IRI and GSM TIP model results as environment for HF radio wave propagation model during the geomagnetic storm occurred on September 26–29, 2011

“…During the past decade, few studies of HF radio wave ray-paths have been done using both numerical ionospheric and RWP models (Andreev et al, 2006(Andreev et al, , 2007a(Andreev et al, , 2007bBlagoveshchensky et al, 2009;Kotovich et al, 2010). The results obtained in these studies include: (1) the model simulation of the HF radio wave propagation in the vicinity of the main ionospheric trough (Andreev et al, 2006;2007b); (2) calculation of oblique sounding ionograms allowing the interpretation of experimental oblique ionograms (Andreev et al, 2007a;Blagoveshchensky et al, 2009);and (3) a model study of the main characteristics of oblique sounding ionograms (Kotovich et al, 2010).…”

However, the above discussed ionospheric models have some spatial limitations, because these are high-latitude ionospheric models (Mingalev et al, 1988;Taschilin and Romanova, 2002) excluding the low latitude region.…”
