The O/O2 concentration ratios above 100 km have been combined with knowledge of reaction and diffusion rates to construct a model of the neutral atmosphere between 80 and 120 km. The average eddy diffusion coefficient is determined within narrow limits by oxygen dissociation and recombination rates and by continuity requirements. The value of the eddy diffusion coefficient compatible with recent mass-spectrometer measurements is about 4×106 cm2 sec−1.
