BrO dSCDs were retrieved in a spectral fit window of 328.5 to 359 nm, simultaneously fitting absorption structures from O3, NO2, HCHO, O2-O2, and the Ring effect. IO SCDs were retrieved in a spectral fit window of 417.5 to 438 nm, simultaneously fitting absorption structures from O3, NO2, O2-O2, H2O, and the Ring effect. Finally, SO2 dSCDs were retrieved in a spectral fit window of 323 to 335 nm, simultaneously fitting absorption structures from O3, NO2, BrO, HCHO, and the Ring effect.
