Short summary
Recently, theoretical and laboratory studies have suggested an additional nighttime channel of transfer of vibrational energy of OH molecules to CO2 in the mesosphere and lower thermosphere (MLT). We show that new mechanism brings modelled 4.3 μm emissions very close to the SABER/TIMED measurements. This renders new opportunities for the application of the CO2 4.3 μm observations in the study of the energetics and dynamics of the nighttime MLT.
