CONVECTION IN THE VENUS IONOSPHERE
McGary, John Edward
Master of Science
Convective studies involving ion flow in the Venus dayside ionosphere are used to understand the nature of the observed O$\sb2\sp+$ distribution. Flows are modeled (not calculated) from previous data and theory which are incorporated to determine the ion distributions for O$\sp+$, CO$\sb2\sp+$, and O$\sb2\sp+$. Current understanding of ion chemistry and related parameters are used in solving the continuity equation in two dimensions to provide ion profiles at different solar zenith angles. To explain the O$\sb2\sp+$ distribution, downward flow with speeds of approximately 500 m/s are required.
