Abstract. An improved kinetic model for the Meinel bands.of OH has been constructed from rate constants and Einstein A coefficients derived in recent laboratory experiments. Using a semiempirical parameterization of the state-to-state rate constants for OH(v) quenching by 02, the absolute OH(v) nightglow radiances are modeled to within the accuracies of the atmospheric constituent concentrations and the radiometric calibrations. Collisional quenching is found to be predominantly multiquantum at high v but single-quantum at low v.
Spectroscopic data and reaction rate coefficients pertinent to ozone in the mesosphere and thermosphere (altitude> 50 km) are critically surveyed. These data should be of use in modeling atmospheric infrared luminescence, measuring atmospheric ozone concentrations by remote sensing, and designing and interpreting laboratory measurements. There is a clear need for additional data on metastable ozone electronic states, additional atmospheric ozone formation channels, collision processes involving electrons and Ions, and vibrational state dependence of reaction rate coefficients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
