Abstract
We have developed a radiative-transfer algorithm for infrared bands in the terrestrial atmosphere and used it to calculate non-LTE vibrational populations of CO2 (described here) and CO (described in a companion paper1). A unique feature of our model is that it incorporates a complete line-by-line transport algorithm. All the effects of the variations in the emission and absorption lineshapes with altitude (for example, due to temperature and pressure dependence) are accounted for. The absorption is calculated on a monochromatic basis for points within each line and then integrated, and this is done for all lines in all ro-vibrational bands in which radiative transport is significant.
