Modeling of O+(2P) dayglow emission.

O+(2P) emission can be used to infer the thermospheric atomic oxygen density hence modeling this emission has a good potential reason. The accuracy of the emission rate of 732.0 nm depends mainly on the production and loss rates of O+(2P) in the thermosphere. However the quenching rate coefficient of O+(2P) by O and N2 given by various studies shows a large variation and hence leads in erroneous determination of O concentration and further in validating the airglow model. The Volume emission rate (VER) of 732.0 nm dayglow emission is calculated using glow model with two different solar EUV flux coupled with the three different estimates of the quenching rate coefficients. However there is a dire need of observation to validate the obtained VER, which will ultimately lead to determine the correct quenching rate coefficient value of O+(2P) by O and N2
