Abstract
A laser heterodyne spectrometer in the 10 micron range is described which enables spectra to be recorded with high resolution and to obtain the true shape of the IR absorption lines. The adjustable temperature and multiple-path optical cell of the instrument permits ozone stratospheric conditions to be simulated. The true shape of the atmospheric absorption ozone line can be obtained by analyzing the solar flux with the spectrometer and its sun tracker. The concentration of stratospheric ozone versus altitude can be deduced by a synthetic spectra calculation and a nonlinear least squares fitting method.
