Ionospheric f-region storms
Web2 dec. 2016 · Due to several complexities associated with the equatorial ionosphere, and the significant role which the total electron content (TEC) variability plays in GPS signal transmission, there is the need to monitor irregularities in TEC during storm events. The F-region storms occur due to sudden increases of energised electrons instilled into Earth's ionosphere. The F-region is the highest region of the ionosphere. Consisting of the F1 and F2 layers, its distance above the earth's surface is approximately 200–500 km. [7] The duration of these … Meer weergeven Ionospheric storms are storms which contain varying densities of energised electrons produced from the sun.
