A Model of the Diurnal Variation in Magnesium Ion Density and Radiance in the Thermosphere.

Abstract

A model has been developed to investigate the behavior of magnesium ions in the thermosphere. The model includes deposition of the atomic metal, diffusion, kinetic creation and destruction of ions, and ultimate removal of the atomic Mg. Transport of the Mg+ by electric fields is also included. A strong diurnal variation in the Mg+ profiles is observed. These profiles are transformed to radiance for conditions mimicking the GLO experiment, to which the results are compared. Key features of the GLO observations are reproduced well by the model. (jg)
