CO2(ν2)-O quenching rate coefficient derived from coincidental SABER/TIMED and Fort Collins lidar observations of the mesosphere and lower thermosphere

Autor: W. D. Pesnell, C.-Y. She, A. K. Smith, A. A. Kutepov, A. G. Feofilov, R. A. Goldberg

Publikováno v: Atmospheric Chemistry and Physics, Vol 12, Iss 19, Pp 9013-9023 (2012)

Among the processes governing the energy balance in the mesosphere and lower thermosphere (MLT), the quenching of CO2(ν2) vibrational levels by collisions with O atoms plays an important role. However, there is a factor of 3–4 discrepancy between
