Abstract
The predicted intensities of the ionized carbon dioxide (CO2+) emission feature at 2890 angstroms and the Fox-Duffendack-Barker bands are 5.2 and 19.9 kilorayleighs, respectively, for a vertical column. Direct photoionization of carbon dioxide by solar radiation contributes 3.5 and 4.1 kilorayleighs, respectively, and fluorescent scattering by C02+, 1.6 and 15.3 kilorayleighs, respectively. Photoelectron impacts are less important.Keywords
