This paper is the second of a series that reports results on the measurements of the absorption cross section of SO2 in the UV/visible region at high resolution and that investigates high temperatures in support to planetary applications. Absorption cross sections of SO2 have been obtained in the 29 000-44 000 cm-1 spectral range (227-345 nm) with a Fourier transform spectrometer at a resolution of 2 cm-1 (0.4500 cm MOPD and boxcar apodisation). Pure SO2 samples were used and measurements were performed at room temperature (298 K) as well as at 318, 338 and 358 K. Temperature effects in this spectral region are investigated and are favorably compared to existing studies in the literature. Comparison of the absorption cross section at room temperature shows good agreement in intensity with most of the literature data, but shows that most of the latter suffer from inaccurate wavelength scale definition. Moreover, literature data are often given only on restricted spectral intervals. Combined with the data described in the first part of this series of papers on SO2, this new data set offers the considerable advantage of covering the large spectral interval extending from 24 000 to 44 000 cm-1 (227-420 nm), at the four temperatures investigated. © 2009 Elsevier Ltd.
