WebFrom ionosondes we extract the plasma critical frequency foF2 which is related to F2 region peak electron density, NmF2, by the relationship: NmF2 = 1.24 x 104 (foF2)2, and the F2 layer peak height, hmF2. From GPS receivers we used the quantity VTEC (Vertical total electron content). We analyzed the seasonal and local time variations of NmF2 ... WebApr 12, 2024 · In addition to TEC estimates, more recent attention has been paid to forecasting the parameters of the ionospheric F2 layer with NNs. One notable example is that the RBF-NN performed well in the short-term prediction of ionospheric F2 layer critical frequency (foF2) (Liu et al. 2009). Together, these previous studies provide important …
