The dayside ionosphere of Venus observed by Mariner 10 may be understood in terms of a dynamic interaction with the solar wind which results in a compressed topside above an “F 2 ledge” consisting of O + and a dynamically unaffected F 1 layer corresponding to a neutral temperature T≃380°K and consisting of O 2 + and CO 2 + . The top of the upper ledge appears to be an ionopause caused by solar wind scavenging of He + , representing a solar‐wind obstacle consistent with the bow shock observations.
