We derive the spatial variations of dust continuum emission at different wavenumbers, which are compared with those of the [O III] 88 micron (113 cm ^ -1) emission and the OH 119 micron (84 cm ^ -1) absorption.

Click on Spectral Database Browser — then Atmosphere Browser — set the wavenumber to 0 to 3,000 which covers the majority of the visible and far infrared spectrum and you can compare the absorption bands of all the various gases.

CO2 has a main absorption band near 15 um (about wavenumber 667) that includes a strong absorption line at that wavelength with correspondingly weaker lines as one moves into the «wings» toward either 13 or 17 um.

The standard tables for absorption of photons by CO2 show that at STP, 50 % of photons are absorbed within 25m and 50m for wavenumbers 650, and 700 respectively.

Phil says: «Where do you get your value of 0.2 emissivity from, what range of wavenumber is it for, why haven't you accounted for the variation of energy over the wavenumber range or the different absorption bands of H2O and CO2?»

The radiation spectrum for temperatures between 300 k and 250 k only includes a single absorption window for CO2 centred on 14.77 microns wavelength (677 cm ^ -1 wavenumber).
