On the Theory of Diffusion in the Ionosphere

Authors


Summary

This paper reviews in a general way the theory of diffusion in the ionosphere, with particular reference to the work of Ferraro. A brief historical resumé is given in Section 1. The equations applicable to the ionospheric F2 layer, and the properties of their solutions at great heights, are dealt with in Sections 2 and 3, while Section 4 gives some numerical considerations bearing on the importance of diffusion in the F2 layer. Section 5 briefly discusses the degree of electrical neutrality prevalent in the ionosphere.
