A comprehensive model is developed using the updated rate coefficients and transition probabilities to study the redline dayglow emission of atomic oxygen. The solar BUY fluxes are obtained from the Solar Irradiance Platform (SIP), and incorporated into the model successfully. All possible production and loss mechanisms of O(D-1) 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.
