Data of

L.T. Molina, J.J. Lamb, and M.J. Molina, "Temperature dependent UV absorption cross sections for carbonyl sulfide," Geophys. Res. Lett. 8, 1008-1011 (1981); DOI: 10.1029/GL008i009p01008

The temperature dependence of the absorption cross sections reported by Molina et al. (1981) has been described by

σ(λ, T) = σ(λ, 295K) exp [B(λ) × (T - 295K)]

resulting in the recommended temperature coefficients B:
