Comments: Using synchrotron radiation as a continuum light source, we have measured the absolute absorption cross sections of SO2 from 2080 to 2950 Å with a resolution bandwidth (FWHM) of 0.5 Å and under temperature conditions of 400, 295, and 200 K. Significant temperature effects are clearly observable throughout the studied wavelength region.
