DECREASE IN CO2 CONCENTRATION ABOVE THE TROPOPAUSE

Abstract

Comparisons between the CO2 telluric absorptions observed in high altitude solar spectra and those predicted on a theoretical basis indicates that the atmospheric concentration of CO2 decreases above the tropopause. CO2 mixing ratios were determined on the basis of the absorptions observed in the 2.7 microns and 4.3 microns spectral regions. The concentration determined by both bands give a value of 2.1.0.0001 as the volume concentration of CO2 above 17 km as compared with the value of 3.3.0.0001 for the surface concentration.
