Rocket observations of the Lyman alpha and Lyman beta day airglow are analyzed using a nonisothermal spherical model of the radiation field. This new model provides, for the first time, a method of determining atomic hydrogen densities in the mesosphere and thermosphere. Interpretation of Lyman alpha data taken between 80 and 260 km is consistent with current mesospheric and thermospheric models, with H density equal to 1.9 x 10 to the 7th/cu cm at 100 km. Analysis of 1025 A data suggests that the emission is dominated by Lyman beta with perhaps as much as a 30% contribution from OI 1027.
