Generalized composite nonthermal line profiles are calculated for the thermospheric nighttime emission from O(1S) metastable atoms based on an extension to the simple relaxation model of Hays and Walker. It is shown that the Dynamics Explorer Fabry-Perot interferometer will enable accurate values to be obtained for the branching ratio of the Q(1S) quency.
