Formation of ionisation layers responsible for blanketing Es during daytime counter-electrojet over magnetic equator
Abstract
A model using photochemistry and transport due to electric fields and gravity wave winds has been used to explain the formation of ionisation layers observed over an equatorial station Thumba (dip 0 deg 47 min S) with rocket-borne Langmuir probes during two daytime counter-electrojet periods. These layers were seen as blanketing E s-layers with an ionosonde at Thumba. Convergence of the metallic ions due to 3D gravity wave winds and a westward electric field appears to be mainly responsible for the observed ionisation layer over the equator.
