A greenhouse effect in the ionosphere?
Abstract
Following a suggestion by Roble and Dickinson that increases in the mixing ratios of mesospheric carbon dioxide and methane will cool the thermosphere by about 50K, this paper examines the consequences for the ionosphere. The cooling and the associated composition changes, as described by Roble and Dickinson, would lower the E- and F2-layer peaks by about 2 km and 20 km respectively, but changes in the E- and F2-layer electron density are small.
