Disk-integrated spectrum recorded by TEXES on February 26, 2014, between 1345.05 and 1345.32 cm^-1 (7.4 μm), showing weak transitions of CO₂ and SO₂. The date and duration of the corresponding observation are indicated in Table 2. The February 2014 run corresponds to the weakest SO₂ content measured at the cloupdtop between 2012 and 2016. Thick black line: TEXES data; thin lines: models. Green: SO₂ = 20 ppbv with cutoff; red (best fit): SO₂ = 30 ppbv with cutoff; blue: SO₂= 40 ppbv with cutoff; black: SO₂ = 15 ppbv, constant with altitude. The spectral resolution is 0.024 cm^-1.
