SO2 absorption cross section measurement in the UV using a Fourier transform spectrometer

Abstract: Absorption cross sections of SO2 have been recorded at 295 K at the resolutions of 2 and 16 cm−1. The 27000‐ to 40000‐cm−1 spectral region has been investigated. The comparison with data available from the literature shows a good agreement between the different data sets (less than 5%). However, local discrepancies, for example at the peaks of absorption, can reach 20%.

“…Sulfur dioxide is typically the third most abundant volcanic gas , and is a trace constituent of the Earth's atmosphere, mainly present in the troposphere (Vandaele et al, 1994). It is an environmentally significant species associated with direct and indirect (acidification) damage to ecosystems (Delmelle, 2003) and is potentially harmful to human health (WHO Air quality guidelines, 2006; Hansell and Oppenheimer, 2006).…”

“…For the SO 2 analysis, absorption cross sections of SO 2 at 294 K (Vandaele et al, 1994), O 3 at 294 K (Burrows et al, 1999) and a synthetic Ring spectrum were included . Since the literature cross sections are given in cm 2 molecule −1 we obtain column densities in molecules cm −2 and concentrations in molecules cm −3 .…”

“…For the SO 2 fit, the spectral window of 316.5-325.5 nm was selected. Two O 3 cross sections at 293 K and 221 K, respectively , an NO 2 cross section at 293 K , the SO 2 cross section at 295 K (Vandaele et al, 1994), the HCHO cross section (Meller and Moortgat, 2000) and a ring spectrum (Vountas et al, 1998) were included in the fit. The spectral resolution of the AMAXDOAS UV spectrometer is about 0.8 nm, and all the cross sections used were convolved with the AMAXDOAS slit function prior to the fit.…”
