The CO2 density profile is decided using the photochmical-eddy diffusion model, and the cooling rate of CO2 15μ band in the lower thermoshere is discussed. These results show that the cooling rate of 15μ band decreases somewhat in comparison with the estimation using the assumption of constant mixing ratio of CO2. The O2(1Δg) density profile which is simultaneously calculated has small second peak near 85km.
