The loss of 1074 g/cm! of ions on # solar cycle may significantly alter the Penetration and absorption of solar uv radiation, resulting ina modification of the constituents, chemistry, temperature, albedo, acale height and motion of the simosphere. It may be easier to explain the structure of the atmosphere of Venus If the tons pro- duced above 170 to 200 km are removed by the solar wind. Atomic oxygen below the Venus magnetopause would be phototontacd and lost to the solar wind. A similar argument could explain the tatlure to observe atomic oxygen in the atmosphere of Mars. {UK) ow Dec. 31, 1769
