Infrared Radiative Cooling in the Middle Atmosphere (30–110 km)

摘要: Abstract The infrared contributions to the heat budget by 15 µ CO2, 9.6 O2, and 80 H2O bands are evaluated for upper stratosphere, mesosphere lower thermosphere as a function of latitude both summer winter. Flux divergences numerically quasi-random band model with appropriate line-broadening mechanism. A general discussion source applicable multi-vibrational level molecule is given, this formulation applied carbon dioxide. flux divergence radiation acts cool atmosphere in 30–110 km height region except vicinity mesopause. Here there small, but nevertheless significant heating which increases value toward pole (∼4K day−1). Centers cooling appear near stratopause low latitudes (∼10K day−1) over winter pole. Thermospheric values may vary factor 4 because uncertainties collisional lifetime t...
