Abstract

The absolute absorption spectrum intensities of carbon dioxide sample have been recorded with a tunable diode laser spectrometer in the spectral range 6350–6364 cm^–1, which is suitable for the in situ sensing of carbon dioxide in the lower stratosphere using a commercial telecommunication -type diode laser. It was found that the typical uncertainty of experimental line intensities is about 1% compared with the values listed in the HITRAN database, which are calculated by direct numerical diagonalization (DND).
