Latitudinal dependences of globally averaged nighttime behavior of equivalent slab thickness, peak electron density NmF2, Peak height hmF2 and vertical total electron content VTEC during winter time, averaged over both hemispheres (time interval: 20–04 LT, years 2001–2018). The equivalent slab thickness observations are compared with corresponding model values (top left, dashed blue line).
