Scientific paper
The paper extends the theory of Hines and Tarasick (1987) for the effects of gravity waves on airglow emissions to consider more complex airglow chemistries, including multiple and multiple-step production mechanisms, quenching, and other loss processes. Relations for the dependence of eta, the ratio of brightness to temperature fluctuations, on emission chemistry are presented in a generalized form which is readily applicable to other emissions. The specific case of O2(b1Sigma-g(+)) airglow is examined for three different proposed chemical production mechanisms. It is shown that gravity wave observations may place new constraints on possible mechanisms for airglow production, constraints that are not obtainable by other means. The specific case of OH airglow is examined in detail for the quenching rates of Llewellyn et al. (1978) and for those of Lowe (1991). Quenching is found to be important to predictions of eta. The results obtained are compared with the limited set of published observations of gravity waves in OH airglow.
