抄録

An analytical procedure to which the multiderivatives of the atmospheric absorption spectrum and of absorption cross section spectra are applied has been proposed in order to retrieve atmospheric constituent concentrations. In this study, the proposed method was evaluated by applying it to real atmospheric absorption spectra. Preceding the evaluation, an open light path spectrometer for acquiring atmospheric absorption spectra was developed. The instrument consisted of an artificial light source, a telescope for both emitting and receiving light, a reflector, and a spectrometer. Absorption spectra can be acquired in the spectral region from UV to visible. The instrument can achieve a high signal to noise ratio and high-speed sampling because it is equipped with a two-dimensional CCD detector. To evaluate the applicability of the proposed procedure, measurements of concentrations of NO₂, O₃, SO₂, and HCHO were carried out together with other instruments. The results of the comparisons showed good agreement for all species.
