Highlights A comprehensive model is developed to study the atomic oxygen redline dayglow emission. The updated reaction rate coefficients and transition probabilities are used in the model. The present model is found in better agreement with the WINDII measurements in comparison with the earlier model. The model results indicate that the updated input parameters are quite consistent with each other. The present model may be used to study the global distribution of atomic oxygen redline dayglow emission.

    Abstract A comprehensive model is developed using the updated rate coefficients and transition probabilities to study the redline dayglow emission of atomic oxygen. The solar EUV fluxes are obtained from the Solar Irradiance Platform (SIP), and incorporated into the model successfully. All possible production and loss mechanisms of O(1D) are considered in the model. The neutral number densities and temperature are adopted from the NRLMSISE-00 model. The ion and electron densities, and electron temperature are adopted from the IRI-07 model. The model results are validated with the help of measurements as provided by the Wind Imaging Interferometer (WINDII) on board Upper Atmosphere Research Satellite (UARS). The present results are found in better agreement with the measurements in comparison with the earlier model. The measured volume emission rate profiles are reproduced quite well by the present model. The model results show that the updated rate coefficients and transition probabilities are quite consistent and may be used in the aeronomical studies.
