Ozone absorption around 10 mum

Abstract

A careful comparison of four sets of ozone line intensities measured independently in the 10 ƒÝm region has been achieved. It is demonstrated that three of the experimental sets agree to better than 2% whereas the last one is consistently 4.4% higher. This is also the case for the ozone line intensities given in the HITRAN database, which are about 4% higher than the values given in the three experimental sets in agreement. New and more accurate transition moment constants for the ƒÞ1 and ƒÞ3 bands of 16O3 were derived and used to generate new line positions and intensities. These new spectroscopic parameters allow one to simulate atmospheric spectra recorded by the Atmospheric Trace Molecule Spectroscopy Experiment better than the existing HITRAN spectroscopic parameters, showing that on a relative basis the new spectral parameters are of better quality.
