Abstract: 
Measurements of the 0-0 band of the Infrared Atmospheric System of the molecular oxygen during early night-time show a non-negligible fraction of the emission which is a remnant of the very high concentration of atmospheric O2(a1Δg) during the day. The importance of this contribution decreases progressively after sunset. The complexity of the photochemistry during twilight, involving fast variation in the concentration of the atmospheric compounds and in the solar fluxes, makes it difficult to study the decay of the daytime emission. We have developed a detailed treatment of the different processes governing the production and loss mechanisms of the O2(a1Δg) at times near sunset and during the night. This model is capable of explaining the remnant observed in measurements carried out by rocket-borne instrumentation. © 1989.
