Short summary
Chemical reactions are key to the energy budget of the upper mesosphere–lower thermosphere, but this process remains poorly quantified. We derived a new dataset of nighttime chemical heating by combining observations from two different satellite instruments. The main exothermic reactions, hydrogen reacting with ozone and oxygen recombination, dominate at different altitudes and vary seasonally. The new results revise previous estimates and provide constraints on the mesopause energy budget.
