The Earth's ionosphere, a natural plasma, is formed by extreme ultraviolet radiation from the Sun and
particle precipitation and is affected by time, season, latitude, and geomagnetic storms. The ratio of the
total electron content (TEC) to the peak electron density (NmF2) of the F2 layer is called ionospheric slab
thickness (τ), which is affected by various ionospheric parameters, gives us the variation in the vertical
direction of the ionosphere. In this study, with ionosondes with URSI codes IF843, PA836, BC840,
AU930, PRJ18, and BVJ03 located at the equatorial latitudes of the Northern and Southern Hemispheres
of North and South America, the τ change between 1-14 February 2022 by dividing the TEC by NmF2
was investigated locally. By comparing τ with the peak height of the F2 layer (hmF2), two clusters were
detected around two different 12-hour curves that varied from region to region. It was found that the
correlation between them was higher during the day and weaker at night. By calculating the angle between the curves, the diurnal variation of the relationship between τ and hmF2 in that region is shown,
and it is seen that the angle difference increases from the equator to higher latitudes. Developing this
research to cover all latitudes on Earth and a longer period will improve our understanding of space
weather.
