Atomic oxygen is an important participant in the energetics of the middle atmosphere. An algorithm has been developed that derives mesospheric nighttime atomic oxygen from SABER observations via a quadratic relationship. Additional outputs include atomic hydrogen and chemical energy deposition rates for seven important exothermic reactions in the nighttime mesosphere. Essential for the derivation is the nighttime hydroxyl airglow measured by SABER. The SABER 2.0 μm channel measures hydroxyl emissions from the OH(9-7) and OH(8-6) transitions. The hydroxyl emission is important because the production of hydroxyl from the reaction of atomic hydrogen and ozone can be related to the recombination reaction of atomic and molecular oxygen. We report results derived from SABER data analysis for the period from January 2002 through December 2008.
