Ionospheric peak height at the magnetic equator: Comparison between ionosonde measurements and IRI
T Maruyama, G Ma, T Tsugawa, P Supnithi… - Advances in Space …, 2017 - Elsevier
The ionospheric peak height in the F layer (hmF2) varies with not only thermospheric
conditions but also dynamic processes in the upper atmosphere. At mid-latitudes, the field-
aligned diffusion and recombination loss determine the hmF2 in the absence of applied
vertical drift. Vertical drifts displace the hmF2 to a new equilibrium position in conjunction
with the field-aligned redistribution of the plasma. In the vicinity of the magnetic equator,
however, the equilibrium state would be different from low and mid-latitudes because the …
