Scientific paper

Odd-oxygen (Ox = O + O3) plays an important role in determining the energy budget of the mesosphere. The rates of important exothermic reactions depend either directly or indirectly on Ox concentrations, as does the rate at which energy is lost through airglow emissions. TIMED/SABER airglow measurements can thus be used to infer atomic oxygen and ozone densities and, through the use of photochemical models, chemical heating rates. This study combines SABER atomic oxygen and ozone observations to study mesospheric variability of Ox. Observations reveal significant seasonal and diurnal variability in odd-oxygen which affects chemical heating rates and the mesospheric energy budget.
