Abstract: Atmospheric parameters in near space (temperature, density, wind field, etc.) have a great influence on the accuracy of the model prediction and the safety of spacecraft operation. Airglow simulation is an indispensable aspect of the inversion of the atmospheric parameter. In this paper, the Volume Emission Rate (VER) and limb radiation intensity of oxygen A(0, 0) band airglow are calculated based on the photochemical model. Firstly, the photochemical model O2 (b1Σg+) was established based on the theory of atmospheric dynamics, photochemical reaction mechanism, and photochemistry. Then, the VER of O2 A-band was calculated, and the limb radiation intensity of airglow is simulated using a geometric path integral along the line of sight. The simulation radiation and its corresponding height are both consistent with the results of AURIC model. Finally, based on the results of the simulation, the influence factors of VER and radiation of oxygen A-band airglow are analyzed.
