Contribution of meteor flux in the occurrence of sporadic-E (Es) layers over the Arabian Peninsula [PDF]

open access: yesAnnales Geophysicae, 2021
A sporadic-E (Es) layer is generally associated with a thin-layered structure present in the lower ionosphere, mostly consisting of metallic ions. This metallic ion layer is formed when meteors burn in the upper atmosphere, resulting in the deposition of
