Abstract

If the atmosphere is uniformly mixed, a mixing ratio of nitrogen to carbon dioxide of 5 percent is consistent with the observational data on the ultraviolet dayglow of Mars. If the magnitude of the eddy coefficient in the atmosphere is similar to that for the earth, this limit is reduced to less than 0.5 percent.
