Numerical Simulation of Ionospheric Electron Concentration Depletion by Rocket Exhaust

摘要

In terms of the diffusive process of the gases injected from rocket exhaust intothe ionosphere and the relevant chemical reactions between the gases and the composition ofionosphere,the modifications in ionosphere caused by the injected hydrogen and carbon dioxidegas from the rocket exhaust are investigated.The results show that the diffusive process of theinjected gases at the ionospheric height is very fast,and the injected gases can lead to a localdepletion of electron concentration in the F-region.Furthermore,the plasma ’hole’ caused bycarbon dioxide is larger,deeper and more durable than that by the hydrogen.
