A temperature-dependent spectra (TDS) originated from the DOAS spectra of sulfur dioxide (SO\n                    <jats:sub>2<\/jats:sub>\n                    ) in the wavelength range of 276\u2013310\u2009nm was introduced, and the relationship between the TDS and the temperature was built through experimental calibration process. This relationship is found to be independent of SO\n                    <jats:sub>2<\/jats:sub>\n                    concentration and can be used for temperature measurements. The experimental results indicated that the precision of the TDS method is\u2009&lt;\u2009\u00b1\u20090.3% for SO\n                    <jats:sub>2<\/jats:sub>\n                    concentrations higher than 150\u2009ppm with the optical path length of 170\u2009mm. For lower concentrations, the precision is estimated to be \u00b1\u20090.4% at 1\u2009ppm. The relative deviation between the temperature measured by the TDS method and that measured by a thermocouple is within 3% in the temperature range of 298\u2013750\u2009K, and the TDS method has a quicker response to the fast-changing temperature than the thermocouple.\n
