Empirical model for variation of the continuum emission in the upper atmosphere. 2. Infrared components

The absolute integral intensity of the IR components of the continuum emission is calculated from the laboratory velocities of photochemical reactions between NO and nonexcited and excited O₃ molecules. The vertical intensity distribution of the continuous radiation spectrum of the upper atmosphere (continuum) in the IR area spans a range of heights of the middle atmosphere from 10 to 15 km. A comparison of the calculated values of the continuum intensity with the results of its spectrophotometric surface measurements in the near-IR spectrum allowed refinement of the coefficient of velocity of the NO-ozone reaction responsible for origination of the continuum emission in the IR spectrum range.
