| COMMENTS: | JPL-2015 recommendation:
170-258 nm, data of
D. Gillotay, A. Jenouvrier, B. Coquart, M.F. Mérienne, and P.C. Simon, "Ultraviolet absorption cross-section of bromoform in the temperature range 295-240 K," Planet. Space Sci. 37, 1127-1140 (1989); DOI: 10.1016/0032-0633(89)90084-6,
260-350 nm, parameterization of
D.K. Papanastasiou, S.A. McKeen, and J.B. Burkholder, "The very short-lived ozone depleting substance CHBr3 (bromoform): revised UV absorption spectrum, atmospheric lifetime and ozone depletion potential", Atmos. Chem. Phys. 14, 3017-3025 (2014); DOI: 10.5194/acp-14-3017-2014
The parameterization of the temperature dependence of Papanastasiou et al. (2014) is recommended for the wavelength range 260–345 nm for temperatures in the range 260–330 K:
log10 (σ(λ,T)) = ∑i Ai λi + (296 – T) × ∑i Bi λi with the following parameters Ai and Bi:
------------------------------------------------
i Ai Bi
------------------------------------------------
0 -32.6067 0.1582
1 0.10308 -0.0014758
2 6.39×10-5 3.8058×10-6
3 -7.7392×10-7 -9.187×10-10
4 -2.2513×10-9 -1.0772×10-11
5 6.1376×10-12
The parameterization of Gillotay et al.(1989) is recommended for wavelengths <260 nm:
log10 σ(λ, T)) = ∑An λn + (T–273) × ∑Bnλn
with the following parameters An and Bn:
A0 = –110.2782 B0 = –1.5312 × 10–1
A1 = 1.0281 B1 = 1.6109 × 10–3
A2 = –3.6626 × 10–3 B2 = –5.8075 × 10–6
A3 = 4.1226 × 10–6 B3 = 7.2893 × 10–9
