Web20–30% to the total ionization rate [Nier and McElroy, 1977]. Even though CO2 is the major atmospheric constituent of Mars at low altitudes and CO2 + ions are the primary ions produced below 100 km, O2 + ions are dominant at low altitudes because most of the CO 2 + ions are broken down into O2 + ions through a subsequent ion-neutral reaction ...

WebThe early atmosphere of Earth is believed to have been a mixture of carbon dioxide (CO 2), nitrogen (N 2), and water vapor (H 2O), with trace amounts of hydrogen (H 2), a mixture similar to that emitted by present-day volcanoes. The composition of the present atmosphere bears little resemblance to the composition of the early atmosphere.
