Atomic oxygen measurement utilizing the resonance lamp technique is described. It is probably the most reliable method in the lower thermosphere even at present. However, its performance has not been sophisticated enough yet. The uncertainty sources are (1) shock wave disturbance around the rocket and (2) correction for the Doppler shift. We must also be careful against the contamination due to the chemical effects of vacuum ultraviolet photons.
Key words: Atomic oxygen, resonance lamp, lower thermosphere.
