Abstract Atomic hydrogen for this model has been inferred from the hydroxyl airglow measurements on Solar Mesosphere Explorer (SME) spacecraft between 10 and 1.3 μbar (80–93 km). During the day Meinel band emission of OH is proportional to the product of ozone and hydrogen. Since daytime ozone has been inferred from the O 2 (1Δ g ) emission, daytime hydrogen can be inferred. Very large annual and semiannual changes are found in this region. At 40°N the summer-to-spring ratio of atomic hydrogen exceeds a factor of 4 at 10 μbar (80 km).
