Stratification of the Low-Latitude and Near-Equatorial F2 Layer, Topside Ionization Ledge, and F3 Layer: What We Know about This? A Review

Figure 19

Electron density profiles from model calculations with drift and no neutral wind (dashed curve), with neutral wind and no drift (dotted curve), and with both drift and neutral wind (split curve) (from Balan et al. [35]). The profiles correspond to 11:00 LT at 4° magnetic latitude at the longitude of Fortaleza during June solstice at low solar activity. Note that the F3 layer does not form when the wind alone is used (dotted curve).
