Ionospheric Response along Meridian for the Certain Storm Using TEC and foF2

For a long time, the equivalent ionospheric slab thickness ? has remained in shadow of main parameters: maximum density, NmF2 (or critical frequency, foF2), and total electron content. Empirical global models have been developed for these two parameters. Recently, several appeared concurrently. This paper compares Neustrelitz model (NSTM), with ?(IRI-Plas) IRI-Plas model, ?(Appr) approximation constructed along 30° E meridian using data from ionosondes. The choice best conformity observational was made, which used to study effects space weather during magnetic storms March 2012. included: (1) transition negative disturbances at high latitudes positive ones low latitudes, (2) super-fountain effect, had revealed explained previous papers, (3) deepening trough. efficiency studying confirmed. advantage is its closeness real data. ability determine foF2 without NSTM insufficient role due accuracy decreasing increasing latitude.
