Paper Abstract

The present work deals with the problem regarding the improvement of the differential optical absorption spectroscopy (DOAS), applied to study the stratospheric ozone and other trace gases involved in this chemistry. In particular, the temperature dependence of the Ring effect and the related changes of the NO2 slant column caused by this dependence is verified. The temperature dependence of NO2 is also taken into account. It is shown that the stratospheric temperature variations of about +/- could modify the Stokes and anti-Stokes Raman component and hence modify the Ring effect. The presented results demonstrate that, if such temperature variations are ignored, the related NO2 slant column could be over- or underestimated of about 10 percent.
