Emission from CO2 Around 2.7 Micrometers from Daylight Atmospheres,

Abstract

A detailed study of the vibrational states of CO2 in the upper atmosphere was conducted in order to enable the calculation of emission near 2.7 micrometers expected for sunlit conditions. New line-by-line computer codes were used to evaluate the solar pumping of vibrational levels and to calculate the limb radiance. Excitation and important vibrational transitions in the altitude range 60-100 km. The dominanceof fluorescent CO2 hot band emission for altitudes below 75 km is confirmed. The spectral distribution, and to a lesser degree the total band radiance, are shown to be very sensitive to collisional interactions. Detailed results are presented and compared with experiment. Originator supplied keywords include: Infared solar pumping, Carbon Dioxide Emission.
