“…The data incompleteness does not allow to sufficiently describe the radiative quenching in photochemical modelling. Therefore, Yankovsky et al [2] presented an estimation of the Einstein coefficients for emission transitions in the O2 atmospheric, IR atmospheric, and Noxon bands based on values of the Franck-Condon factor from [71]. [62].…”

“…In the last decades, it has been shown that emissions of excited oxygen atom O( 1 D) and molecular oxygen in electronically-vibrationally excited states O 2 (b 1 Σ + g , v) and O 2 (a 1 ∆ g , v) are related by a unified photochemical mechanism in the daytime mesosphere and lower thermosphere (MLT). A recent model which describes this mechanism is the YM2011 model [1,2]. However, before proceeding to the discussion and description of the model and its updates, we would like to present a brief overview of previous studies.…”

Atmospheric emissions of atomic and molecular oxygen have been observed since the middle of 19th century. In the last decades, it has been shown that emissions of excited oxygen atom O(1D) and molecular oxygen in electronically–vibrationally excited states O2(b1Σ+g, v) and O2(a1Δg, v) are related by a unified photochemical mechanism in the mesosphere and lower thermosphere (MLT). The current paper consists of two parts: a review of studies related to the development of the model of ozone and molecular oxygen photodissociation in the daytime MLT and new results. In particular, the paper includes a detailed description of formation mechanism for excited oxygen components in the daytime MLT and presents comparison of widely used photochemical models. The paper also demonstrates new results such as new suggestions about possible products for collisional reactions of electronically–vibrationally excited oxygen molecules with atomic oxygen and new estimations of O2(b1Σ+g, v = 0–10) radiative lifetimes which are necessary for solving inverse problems in the lower thermosphere. Moreover, special attention is given to the “Barth’s mechanism” in order to demonstrate that for different sets of fitting coefficients its contribution to O2(b1Σ+g, v) and O2(a1Δg, v) population is neglectable in daytime conditions. In addition to the review and new results, possible applications of the daytime oxygen emissions are presented, e.g., the altitude profiles O(3P), O3 and CO2 can be retrieved by solving inverse photochemical problems when emissions from electronically vibrationally excited states of O2 molecule are used as proxies.

“…At lower altitude, the quenching-related decay of O 2 (a 1 ∆ g , v' = 0) is significant because the probability of quenching determines the lifetime of O 2 (a 1 ∆ g , v' = 0), while at higher altitude, the local thermodynamic equilibrium (LTE) is broken because of the presence of constant sources of excited molecular oxygen due to O 2 and O 3 photodissociation. O 2 (a 1 ∆ g ) is formed mainly by photolysis of O 3 in the Hartley band below about 100 km and by energy transfer from O( 1 D) above that altitude [20,22]. The collisional quenching of O 2 (b 1 Σ g ) with N 2 and O 2 also contributes to the production of O 2 (a 1 ∆ g ), especially at 65-85 km.…”

The O2(a1Δg) emission near 1.27 μm provides an important means to remotely sense the thermal characteristics, dynamical features, and compositional structures of the upper atmosphere because of its photochemistry and spectroscopic properties. In this work, an emission–absorption transfer model for limb measurements was developed to calculate the radiation and scattering spectral brightness by means of a line-by-line approach. The nonlocal thermal equilibrium (non-LTE) model was taken into account for accurate calculation of the O2(a1Δg) emission by incorporating the latest rate constants and spectral parameters. The spherical adding and doubling methods were used in the multiple scattering model. Representative emission and absorption line shapes of the O 2 ( a 1 Δ g , υ ′ = 0 ) → O 2 ( X Σ g 3 , υ ″ = 0 ) band and their spectral behavior varying with altitude were examined. The effects of solar zenith angle, surface albedo, and aerosol loading on the line shapes were also studied. This paper emphasizes the advantage of using infrared atmospheric band for remote sensing of the atmosphere from 20 up to 120 km, a significant region where the strongest coupling between the lower and upper atmosphere occurs.
